Rear Fog/reverse Light Clust Makeover

Recommended Posts

Hi all. Thought I'd posts my first DIY post. I've seen other posts that cover this makeover but none of them seem to cover the job from beginning to end or using silicone sealant/adhesive.

Seeing as its a well known fact that these light units suffer from product quality issues, as the seal seems to break on every one! This is a cheap and easy makeover to do and took me about 45mins to do both sides from begining to end.

First thing you need to do is take the light units out. Open up your boot lid and remove the interior trim.

Remove the two clips at the base of the side that you wish to remove. This can be done with a flat blade screwdriver. The clips have a top section that pulls out and this releases the whole clip.

Next you have to pull down the trim and unplug the units electrical connector

There is also a clip which is a part of the unit itself. Pull this down and it will release the whole bulb housing

Now the only part left is a nut at the end of a plastic section. Undo this nut completely off.

Now you're set to remove the lense. Pull the lense out, pulling the inner edge up first. This will also allow the lense to pull away from the outer edge which has a lip

The next part is the clean up

The fact that you're wanting to do this makeover means that your seals have already gone on the unit. You can try heating the remaining seals with a hair dryer or even put the units in an oven for a shot while to soften the seal but I found with a little bit of force, the rest of the seals just crumbled away and the lense seperated

You can see from the pics just how much gunk gets in the units! As the unit has been letting in water and it has been sitting at the bottom, it completely destroys the reflective paint. Just goes to show if you can catch them sooner rather than later, you'll be able to make them look even more like brand new

Mine as you can see we're pretty gunked up but luckily most of the damage is done to the bottom section which is hidden behind the red lense.

I soaked mine in warm water quickly, then used a toothbrush to remove the worst. *important tip- for sections that you will be able to see through the clear lense, just gentle use your finger to clean them to avoid any reflective paint loss for where you'll see!

Next I gave the lense a quick going over with standard car polish to bring the shine back out

The next part is the re-seal. I have seen another post using a sealing tape, but I wanted to make sure these were sealed tight so I wouldn't have to do them again. I bought some clear silicone sealant/adhesive from halfords for £4.99. It's pretty much designed for the re-seal of light units. I applied one line of the silicone to the ridge of the lense where the old sealant use to sit

Press the back of the unit together with the lense, then hold in place with a bit of masking tape

Be careful with the sealant around the clear section as if you put too much on you'll see a bit of the sealant. Leave it for about 15 mins to set and it's good to go back in!

Complete the first steps for removal in reverse and gone are those dull mold filled light units!

And before anyone says it, my next job will be to wash the car! :)

Cheers. Yeah they turned out ok. Look soo much better than that moldy dim look. The best part is that you can have it all done in less than an hour and it only cost £4.99 to do it. Beats buying two off eBay for about £20 odd for each side.

Good write up. I've just done one of mine, as it started taking on water when it rained and dripped into the boot when the boot was open!

Hahaha yeah mine did the same! Use to soak anything in the side sections of my boot.

My only word of advice on doing this is just be very careful and take your time with seperating the lense. It makes lots of crunching sounds and would be all too easy to crack a lense.

Seems that the sooner you catch them the better, as the water sitting in the units destroys the reflective paint and it just runs off when you touch it.

Just done mine. thanks for the info! Unfortunatly, the silvering on both of them had all but gone because they had both separated at just a small place a long time ago and let in moisture. I did not notice till one let in water during a wash.

I've been waiting for a thread like this. Thanks very much! :thumbsup:

I bought a pair of Depo replacement lights to be going on with, as my originals let the car down badly. The plan is to refurb the originals, as detailed here, for refitting sometime in the future.

when putting them back do you have to put the sealant on the back of the lights to bond with the car?

No only do the lens or you won't get them back out mate.

Thanks for this DIY! I hope you dont mind me asking... I was just doing this for my own car which is a coupe and I'm having trouble getting the lining/trim off. I see on this DIY and others that the lining seems to just bend down really easily but I can hardly make it budge even though I removed all of the clips (i also undid the tools compartment).

Any idea what the problem is? I thought the lining would just pop right off but apparently not!

Thanks in advance!

Hi,all I did when I took mine off was remove the clips round edge of boot and mine just pulled back enough without removing it all,I even left my tool kit in place. Make sure you've removed all the clips round the edge only thing that can hold it I think.
