Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Fog warning and reversing lights

At the risk of being a nuisance I have yet another question.
After reading Dave's article in the latest Miscellany I decided to have an inspection of the front indicator lights and the fog and reversing lights.
Dave said in the article that the front indicators were prone to spray and sometimes filled with water. How right he was, one of the bulbs was totally rusted into the holder and had to be extracted with brute force (hammer and pliers)I did manage to save the holder though.
I then thought it may be an idea to inspect the fog and reversing lights. I managed to unscrew them but the whole fitment unscrewed. The lens seems to be held on to the fitment with rivets or studs and not the usual screws. As far as I can see there is no way of removing the lens to replace the bulb. Surely I don't bin the whole unit if a bulb or a lens needs replacing?
Any advice would be very gratefully received.

I haven't been in there for a while, but.......
The two rivet heads visible are blind rivets and will prise out with a screwdriver, leaving two holes. They are decorative only.
The lenses for fog warning and reversing are silicon sealed onto a large pressed metal base which screws direct into the rubber mount. Last time I looked I could get at the bulb, because I remember the connection was poor.
So have another look. If necessary you can take the whole thing off by accessing the rear through the spare wheel well.
They don't refit well and need some silicon lubricant to screw the whole way in.
Note this is where these lamps have rubber mounts, similar to the front indicators, not the current faired in lamps.

Thanks a lot Dave, I'll have another shufti tomorrow.

Hi John

If the rear lights are the same as mine they do leave a little to be desired. I recently changed a lens. My fitment was also secured to the lens with a single bead of silicon sealant. They will however separate with a slit from a scalpel and a hearty twist. Had to clean up and re silicon to assemble.

I’m just in the process of looking to replace the complete light units and mounts with something a little more conventional. The large rolled thread on the fitment that screws into the rubber mount doesn’t fill me with confidence. Mine are currently taped up with black insulation tape as I fear I may lose them on a bumpy road.

I have the same rear fog and reverse lamps and have not found they leak or work loose - plenty of bumpy roads here. Perhaps they are better sealed against water than the front indicators for example, which may be why they were chosen for that location.
I did work out that they could probably be replaced using the rubber mounts for front indicators (the angle is the same but inverted), plus Lucas fittings as per the upper rear lights, but haven't done so.

Thanks for all the useful information folks. I think MMC must have raided the British Leyland rejected parts bin for all their "Prince of Darkness" accessories.
