GTV headlight poor? The easy,quick way to clean the projector assembly!

Ok, we all know that the dipped beam on the GTV leaves a lot to be desired.
Many owners complain that the beam pattern doesn't project far enough!
So many owners sort very expensive and time consuming solution's.
These include illegal 100w H3 bulbs, hid conversions and even sticking their head light assembly in a hot oven and stripping it all down completely! Even if you do this successfully, chances are you will end up breaking a plastic clip, lens or even the vital gubbins completely!

There is a simpler solution to this issue though.
Remember when the GTV was a brand new car, did owners complain about the poor headlight clarity then?
The answer is simple, the projector lens accumulates dirt and stains over the years. This in turn is due to bad bulb fitment leaving seals askew and then the continually heating up of use drying that grime to the inner lens.
Sure you can separate everything to clean it but it's risky without a spare set of headlight's, just in case!

Easy fix is to remove the bulb from the rear completely.
Spray a small amount of glass cleaner through the bulb hole. Let it do its work and repeat again. Use a can of compressed air or an air line duster attached to your spare tyre to force the dirt from the top of the lens to the bottom.
Now as a belt and braces method, spray some isopropyl alcohol (maplins) and dry immediately with the air duster followed by a hair dryer on full heat and max blow just to make sure all the fluids used are dissipated.
Refit your bulb and holder PROPERLY!
TIP: the L bend connector of the bulb always should point down once the bulb is twisted 90 degrees to secure it an maintain the correct beam pattern.
Now go to a friendly mot garage and bung them a tenner to check and adjust your beam pattern correctly while your headlight adjuster switch at its minimum height setting.
Job done, no drama, no damage, cheap as chips because you can use the products you've purchased on other jobs and you have your night driving vision back awhile as it can be!
Cheers
Graham.

Part 2
If it's the outer plastic lens that has dirt on the inside, the chances are it was the main beam bulb seal that let the grime in!
Don't muck about. Drill a 6mm hole slowly and carefully at top corner of the side of the clear plastic from the wing facing inwards between the chrome plastic and the lens itself, while using a vacuum cleaner to grab the swarf, remember a drill bit will drag it out, not force swarf in. It won't affect your beam pattern if you position the hole correctly. A 6mm rubber grommet can be bought from any motor factor or maplins etc for pennies before you begin!
Follow the cleaning method in part 1using the 6mm hole and main beam bulb hole to gain maximum coverage of the cleaning fluids and drying.
Now you have an as new headlight plus the bargain of a grommet hole to allow any condensation to dissipate if needed during the winter months.
Have fun
Graham.

Yep, using the 6mm hole and main beam bulb entrance, simply attach a length of washer jet tubing to a vacuum cleaner pipe with duct tape, insert the pipe and start cleaning them out, you'd be surprised how much suction it creates and you just twist the pipe into the direction you need to get in all the crevices.

Cheers Graham, I'll give it a go and try the same method for getting rid of the family of spiders in my wing mirror too.

Is that a dipped or high beam conker?
