In my case, the coloured lenses have perished and have the typical 'old car' lens cracking, and the glue holding them to the backing/reflector is almost all gone from being out in the weather. The colour seems to be ok tho, no fading.
My GH is off the road at the moment under "restoration" (aka the car port), so it'll need to pass a roadie too.
From what I can tell from a bit of searching through pictures on SG, the 'leading' or outer edge of the indicator section of the GH tail light assemblies are vertical, whereas the GJ is on a slight angle.
Hmm, may have just answered my own question
I am thinking of making my own tail lights using off-the-shelf LED sealed cluster lights of the appropriate colours, like you see on utes and trailers, and mounted on sheet aluminium that I'd fab up to mount in place of the original reflector housings.
If I go through with it, I'd expect a lot of negative feedback, but what can I do? GH tail lights are so hard to find. Necessity is the mother of invention!
