Of course, yes, very true! I'll certainly look into that when some new sidelights are ordered!

I have taken JABAWOKJAYUK's advice and installed the 8 LED side lights from ebay. Great. No issues. Thank you. Think I'll slowly but surely change quite a few of the bulbs!!

Incidentally, since I swapped the one faulty one its all been fine with no canbus errors, so it looks like its definitely a manufacturing issue with some of the LEDs.
Mine arrived today - great service from that eBay seller. I think I'm image-limited here, so I've uploaded a few pictures to a new Flickr set.

Conditions weren't great for taking photographs of lights, however hopefully you can see the difference it has made. I'd crudely estimate that the brightness has doubled, and of course the white is dramatically different at 6000K.

They're probably good enough to be left on permanently as running lights if you wanted. The old filament bulbs looked to be very poor - the blue coating was peeling off and they're clearly from the budget end of the market.

Changing the bulbs wasn't too bad. Twisting the weather-sealed cap off was fine, and generally everything just seemed like it hadn't been opened for 3 years. Getting the bulb itself took around 10 minutes on the first side. I couldn't find a manual online, however in true man fashion just waded in anyway. Using the gf's mirror I was able to see what I was aiming for, and I tried to turn it one way and the other. That didn't work so in the end I just pulled a bit harder and it came out ok. Again, it just felt as though it had bedded in a bit having not been released for 3 years. The other side came out fine, and both went in relatively easily.

I now have a couple of these left over - I'd also bought these as possible alternatives but having seen the success of the others decided not to fit them. Any ideas on where these can fit? Will they be suitable for any interior lights?

They look pretty good - gonna get some ordered myself!

The ones you have spare look like the ones I currently have as sidelights. I believe they can be fitted to the puddle lights and interior map-reading lights. They can also replace the numberplate bulb if they're CANBUS error-free ones.

Thanks for that. I'll try and prise off the plastic for the interior lights and plug them into the map-readers. They're all CANBUS.

I've just popped back after a quick trip out, and the weather has turned nasty offering some poorer light for a better photo. I think these will look really good at night, but for now here we go - IMG_8814 | Flickr - Photo Sharing!

I'm sufficiently enthused to step up the hunt for a decent HID conversion kit now.

Can anyone help on removing the interior light dome? I've given it a good jiggle, but can't see where the retaining clips are. I'm concerned that if I force it any harder then I'll risk doing some damage.

I havnt yet seen them at night yet as have been to busy to check but they look good! Way closer to 6k than the 8 led ones, and will look good against the HIDs.

Check the start of the thread fir advice, but it cones off from either side with a little force. 3 clips per side hold it in place against the roof lining so be careful and brave in equal measure!

Finally grabbed a couple of pics of the new LEDs. Must say they are way better than the 8 led ones!

Looking good

I just ordered this HID kit to see how much of a difference it will make - http://www.ebay.co.uk/itm/3304436434...#ht_4171wt_905

After a week off this week hopefully I'll have time to install it next week.

If the spring steel clips starts bending up and out you will penetrate the roof lining. Pull it a little way down and you will see the three metal spring clips each side. If the clips refuse to let go you can use a small flat screw driver to push the clips back inwards (towards the light module) to let them all release.

The light module does take a surising amount of effort to release. Also do not pull/push on the clear plastic (lens) part as this is only lightly bonded to the coloured plastic portion of the light module. If in doubt push the module back and start again. FYI there is a plastic "female" recepticle that is bonded to the roof that the module (both front and rear) clips into!

Hope that helps!

That's a big help - thanks. I'd given up, having started to loosen the clear plastic.

I'll try again at the weekend.

Have been interestedly following the thread and am completely confused (as normal) about the best to get. One thing, for instance, in my destruction manual, front indicators are PY21W, but rears are P21W. So what's the difference. Sometimes a single digit can make a lot of difference. There seems to be so many choices I guess I'll just have to get some and see what happens.

The front indicators are chrome where as the rears are normal clear bulbs. We don't have a definitive answer for replacements to the indicators or tail/stop lights yet so feel free to get some and join the investigation! Just make sure you post your findings for everyone to learn from

Look good, but not cheap!

I have some of those 13 SMD sidelights now on order - think I'll put the current 8SMD ones on the map-reading lights, as per the instructions above! I take it the whole silver light unit comes out?

They look like the standard crappy LED tail lights you've been able to buy on ebay for years.
I bought a pair of the 'standard' LED type a few years ago and as soon as I fitted them they came straight back out and sent back as they weren't bright at all.

They look interesting, but doest the 159/Brera already do this? I know when I stamp on the brakes in my TI at speed my Hazards kick in automatically, so although I like the idea, its overkill for the cost on our cars.

I am still waiting for the spider lights to arrive..... very long lead time from the US of A!

Just wondering if flashing lights are sort of illegal as per rear lights on pushbikes?

It would be nice if someone (JabawokJayUK??) could post a quick summary of The Latest State Of The Art, preferably with links to seller for each option - this thread has got very confusing.

With thanks in anticipation ...

Bounce back to the first post in this thread, I updated it with the knowledge, pictures and links so far and will continue to do so as we determine decent options!

Guys, word of advice from someone who is an LED specialist in lighting;

The quantity of LEDs is irrelivant - different LED manufacturers have different luminous outputs.

the wattage of the LED unit is irrelivant - wattage is a measure of power consumption, not light emitted. A bad LED might have a lower lumen per watt efficacy eg 10lumens for 1 watt, vs a good one at 100 lumens for 1 watt. As the power consumption of lighting on a car is not an issue (unlike your home etc...) the low power of an LED is a pointless exercise.

The light beam spread must be close to a conventional lamp, as the reflector housing has been designed around the centre point of the origenal lamp. An LED alternative cannot match this, so the refelctor will not be as efficient, so will loose levels of efficiency - eg the LED version will need to generaly need to output more lumens than an conventional lamp, just to achieve the same percieved output on the outside of the car (known as the luminaire lumens).

Colour temperature - Cheap LED manufacturers may not have tight tolerence control of their LEDs, so one light might appear a slightly differennt colour to the other (Hella had this issue on the recent A4's headlights).

So unless you are doing this for the following reasons, its going to be a case of trial and error & pointless expense in swapping over to LED lamps;
Improve drivers reaction time behind you.
match sidelights to Xenon colour temperature
your vain & doing this for no other reason than to............

I know my shi2 when it comes to LEDs & lighting. The majority of suppliers on ebay etc... dont provide you with enough information to be able to make qualified decisions as to wether these will be truly suitable.

But if you insist on doing this, go to lucus or some such website, find out the Lamp lumen output of the patrticular lamp you are looking to replace, & make sure that the LED lamp you are buying at the very least states the lumen output, (which would need to be 10-20% more than a lucas lamp, to ensure the reflector losses are allowed for.

Thats my 2 penith worth.

Thanks for the input and advice As you seem to "know your shi2" can you suggest any good options / sources etc for LEDs for our cars then?

We are all in the trial and error game at the minute, and despite it being a pointless expense for some, overall others will benefit from our mistakes so I don't see it as entirely fruitless. Isnt that what these forums are all about?

I fitted my HID upgrades this morning. Not too bad a job - about 30 minutes. The trickiest part was putting the weather proof seal back on, as the wires need to come out the side. I was going to drill a small path however there was sufficient flexibility to literally just jam them in the side.

One done, one not

Did you not need the kit with the decoders becuase of potential CANBUS errors
