I am replacing my old, leaky, mismatched clearance lights with new self-contained LED lights (GROTE G5052 and G5053).

I cleaned up all the old goo that was sealing the old ones and installed the new ones with nice new foam gaskets.

My question, should that seal up good? Or does one need to put silicone around them still? I would assume the foam should stop the water?

And what about the 2 screw holes on top? Should one plug them somehow or should they be fine? Trying to eliminate water getting in....

Couple pictures...

Do not use silicone anywhere on the coach.

Cleaning it up is a great start.

I drill out or remove the fasteners that are in place, and use "Well Nuts" with Stainless fasteners. They are self sealing.

I put a bit of "RV-GOOP" around the wire area. It's non-silicone, so it won't foul the surface for painting later.

The screws should have an o-ring type gasket that seals between the head of the screw
and the exterior of the lens.

The foam won't hold up forever, but I will expand on what Harry said about not using silicone. What he meant was don't use it on the exterior. No matter what anyone might say, it does NOT hold up to sunlight.

Use polyurethane caulk instead of silicone, and use painter's tape to mask off where you don't want the caulk. Protect that foam gasket from the elements.

I bought well nuts and screws for this purpose...but once I removed the lights I found the original fastner were in good shape and the original screw threads were 100% without rust... so I decided (cause time is running out) that I would re-use the existing fasteners (new screws) for now.




thanks for the advice all!

Travis,

I too installed Grote clearance lights in Double Trouble and found the same thing you did. That was in 2008 so far so good. Good
enough for me to buy another set for my Kingsley.

What size "we'll nuts" did you use? I discovered after our first hard rain this week (purchased '74 GMC in June) that there was a drip drip drip from the windshield gasket inside above driver and noticed the plastic clearance lens is really loose.

I use 3/8" diameter x 1/2" reach neoprene "well nuts" with brass threaded
inserts I believe that the threads are 10/32. The LED LIGHTS will determine
the overall length of the stainless steel filister head, Phillip's drive
hold down screws. I use 1 1/4" fully threaded ones in my assemblies. Your
assemblies will vary. If you are trying to use original clearance lights,
good luck with the leaks. You are fighting a losing battle.

If the lense has not been replaced, you need to replace them as the UV has
deteriate the lense and the inner gasket also needs to be replaced

Thank Jim. I just replaced all 5 front lenses, lens gasket and body gasket purchased from your business. The OEM nut attached to the top was excellent just the screws need replacement with stainless screws (weekend project). I will be water testing tomorrow then moving to the rear clearance lights.

On another subject, I just finished a complete front suspension rebuild including a steering box replacement from you folks but steering is still wandering left, right, left, right. I provided the GMC maintenance manuals for an explanation of the height adjustment and I know they got the height adjustment correct as they wrote down all of the settings including front camber. But I am not sure the shop adjusted rear wheel camber. I read here that a maladjusted camber on the tandem wheels can cause wandering. I have a tru-track that needs installed but not sure it will solve steering wander. Any suggestions would be appreciated.

You should really take this to a new thread so others can benefit from group knowledge.

Here is a post copy/pasted to this that I posted a while back. HTH

Most of the time when someone complains of this kind of steering issue, the steering gear is no longer on "high point'. I'm guessing that at some time in the past, someone took your steering shaft apart and did not put it back together right. There is a very specific procedure that needs to be followed to get it back where it belongs. Alex Ferrara has mastered the art of putting it on high point and cured something over 100 GMC's with handling manners. So, driving your coach to Florida to have Alex F. do the adjustment on your steering box is not practical. So check out this set of instructions posted on the GMCphoto site of how to do high point.

Let us know how things turn out.

Will do next week. Unfortunately, I don't have a level driveway to do work myself so I have to rely on a local shop for all maintenance.
