Fiesta rear lights remove advice

[TVRSJW]

Could anyone tell if the fiesta rear lights are bonded in ? And what is involved in removing them ?

Assume remove the carpet pods and are they bolted or screwed in ? Any sealant to remove ?

Many thanks

Mine were just held in with 3 self tapping screws with some foam tape (not double sided) between the body and the lamp unit.
The mods to make a stock fiesta unit into a TVR lamp are first hacksaw all the captive bolts off, then drill the 3 holes to hold it in place with self tappers. When I did mine I made templates out of masking tape and drilled the new holes which of course did not work so I fitted the lamp so it was snug and drilled new holes in situ and screwed it into place.

Many thanks , not replacing them wanna take them out and clean the condensation off lenses from the inside

I have already drilled small pilot holes in lenses but not worked

I do understand water could be getting in but it’s a new boot seal and that the sealant on the lense may need to be re/done but......I can’t do that at the min as car lives outside and from what I’ve read it needs a warm dry day to do the lenses else the moisture will be trapped again and would have to leave the lenses taped up to set overnight on the drive ! So not ideal , so thought process was if they are easy to remove the clusters can clean inside of lenses maybe try and coat it with some anti-fog and hope for the best ! There never like this in the summer even if it rains they stay clear , only in winter with temp change they mist and do have water droplets inside

Just didn’t want to break anything !!

OP, condensation in light clusters is a fact of life.

Unless you 'hermetically' seal the unit, the atmosphere will enter the cluster via the lamp holders/other routes. When the ambient temperature drops, the water content of the atmosphere condenses out onto the lens/cover to a greater or lesser degree.
Our recent weather - cold and damp highlights the issue. The atmosphere, very close to 100% relative humidity, enters the unit finds the lens, now with a surface temp of close to zero degrees and the water content drops out onto that cold surface.

Are the pilot holes near the top of light?
The condensation will escape as vapour so it helps if the holes are near the top.

This.
You could try to reduce that humidity by placing dehumidifiers in the boot; the Unibond Aero 360 ones work well, but do remember to remove them before driving!
I have seen bean-bag affairs containing dessicant but I don't know how effective they are.

[Spunagain]

Just a thought, are you running with LED tail lights? Perhaps driving with sidelights on and old fashioned incandescent bulbs would warm it up enough to evaporate the condensation?

[TVRSJW]

Just standard bulbs , never have lights on as always in daylight but could try that , like a I say above get the whole concept of it and understand why but didn’t know if cleaning inside of lense and using anti fog may help ?

They seem to be ready to remove given advice above so prob worth a go !?!

Mine used to mist up when I first bought it, a year ago. I cut out the covers, cleaned them all and then resealed them in with sikaflex as well as drilling a couple of holes in each cover. They no longer mist up, and that is with full LEDs.
I think resealing them made the difference rather than drilling the holes personally, but the combination has certainly worked for me. The car is kept outside under a carport with an outdoor cover, so it still gets cold etc.
