I think the same concept will apply to these - there are two issues. They allow moisture in from poor sealing, fixing that will just create more natural condensation. 2 years ago I applied a bead of RTV along the seam on both tail lights to keep moisture out. See pic.


RTV Bead applied to seam

This spring I will be drilling breathing holes along the top and sealing them with similar Goretex patches used on the headlights.
I may also install a one way valve on the lower side to permit any accumulated moisture to drain if the housing was somehow penetrated.

Thanks, just ordered a few packs of the same patches you used and will attack the headlight and rear light issue. Not driving this car around with the lights filled of condensation.

Anyone have a pic of inside the rear taillight housing. I have them removed to add a couple of Goretex patches but as I stated above I have sealed around the lens and I don't want to take them apart to drill the necessary breathing holes. If I knew where the circuit board and components were inside I can drill confidently without taking them apart. I can't find any pics of a dismantled taillight - if you have some please post.

Hereís a pic from the outside of my housing. I drilled about 6 small holes on the top and one larger hole in the back bottom right corner (low point on the wheel side of the light). Iíve notnhave any issues at all since I did this mod.

You will also need another hole (or 2) in the back bottom right corner of the housing. I havenít had any issues at all since drilling these small holes.

Youíll notice the condensation in my light lens in the pic, took about a week to fully dry out since I did this mod in January and didnít drive the car to much.

Iíve since added 2,000 miles since January, no issues at all.

Thanks Matt, I didn't see these pics before I went ahead - It was pretty simple. I drilled a 1/16" pilot in the two areas I wanted to vent - one on the top at the inside of the light and one one the bottom toward the outside of the light. Then I used a piece of wire at 90 degrees to sweep the area inside the tail light housing for any interference. There was none for the areas I needed (about 1"x2"). I went ahead and drilled the rest of the pilot holes then opened them up to 1/4" and applied the Gore-Tex patches on top and bottom. Lights are back in - In all took about 70- mins.

I don't have condensation issues on these clear tail lights but did this as a preventative action. Since I had fully sealed the tail lights last year the design is similar as the headlights in that they need to breathe in order to dissipate the natural condensation. Now they are fully sealed from external moisture I needed to ensure that the air could move in and out of the housing to equalize the environmental differences (temp, humidity etc.).

Here's a few pics:

AM V8 is an unknown quantity at this point
Hi All,

With regards to the headlights, I also tried every thing, literally, holes, patches, silica, time and money all wasted.
The Aston light is long and traps the hot air, it has many leaks so moist air gets in, thus heats up, rises to cold lense and condensates, no air flow to remove.
I am in the AMOC and saw the details about a Venting Kit specific to a V8 Vantage so I bought one from AM Upgrades, all I can say is brilliant, quick to fit, quality fittings and wiring loom, this is a picture of the kit and guess what, it works.



For more details, contact them at [email protected]<span style="color:#000000"><a href=...com</a></span>

Putting aside differences of opinion for a moment on what has caused this widespread issue, or remedies to correct it - the matter of the condensation can lead to failure of headlights, turning indicators, & brake lights - making this matter truly a safety related issue. The NHTSA (in the USA) is the most powerful of any national org to deal with these matters. If it has enough information and incidences it can conduct an investigation. It can also force manufacturers to correct identified safety deficiencies at no cost to the consumer. Given the low production volume of these vehicles, the complaint percentage thresholds to trigger further action would be relative.

To file a US vehicle safety complaint you need your VIN: If you have pics of the condensation in either tail lights or headlights you can attach them to the online form- but that is not necessary. The whole process takes under 2 mins.

In Canada you file the same complaint here:
