So I gave up and still use the originals

You got any pictures of what the LED replacements looked like mate?

Just need to know the resistance of a 5w 12v bulb, which I think is voltage over current. A 12v 5w bulb will draw a max of 2.5amps (please someone correct if im wrong on this!). I think R = V/I which would be 12/2.5 = 4.8 ohms as a loading resistor. so with that load across the terminals of the bulb the computer should think its a normal bulb.

If this is right ill get the resistors, fit the bulbs and take soem pics as they are extremely white!

I really want tog et these bulbs working

To be honest all this ohms, volts, amps, current, resistance etc I forgot the day I no longer needed it. i.e when I was 18 years old, wish I could help, and wish I could actually remember any of this. If only when I was 18 years old that 8 years later all that information would actually come into use (Not much use for all that malarkey for my career path)

If you get it to work then pop a picture and tell us folks how to get it work, the LED lights sound cool! How much they cost you?

The bulbs were only a tenner. ill see if i can find some resistors tomorrow and try it....

If you put a 4.8ohm resistor across 12V (up to 14V+) then it will have to disipate between 30 and 41Watts - that is a fair amount for a resistor.

To model a normal filament blub using an LED and a resistor you need to statisfy the equation R = 144 / (OriginalBlubPower - LEDBlubCurrent*12).

Great! Thanks. I thought my maths was a bit off! ill get some resistors and have a go later.

might be worth a shot being so cheapJust come across these on the fleabay, are they similar to the ones you have mate?

Thanks for the update! Just think, it will be worth it though! :lol:

Been looking at this aswell, if you want to fit something for day and side light then your going to need a stop/tail light replacement LED bulb,

perhaps something like these http://global.ebay.com/2_X_7440_7443_WHITE_15_LED_BRAKE_STOP_TAIL_LIGHT_BULBS/290366480360/item.

Best to compare the fitting on the base of the original 21/5w bulb with the one your thinking of buying, not got round to taking mine out yet.
