Trailer Clearance Lights...ARGH!!!

you will probably twist them off. they are probably self taping if they are in alum and if you can without melting anything heat up the alum with a little mini torch to expand the hole alum will expand faster than steel. it wont take much.

 

The steel screws oxidize with the aluminum side rail, and it works just like lock-tite. I recently replaced all the lights on my Great Dane reefer with LED's and had to re-drill holes for at least half of the lights on the bottom. I feel your pain on this one. But it's not just with a Dane, all of them do it.

 

just be careful not to melt wires i ment to also say to get a junk screwdriver put on the screw and tap it with a little hammer to break the oxidied alum that may work also

 

If you don't want to spend all day just fixing a couple of lights, the quickest way when the screws are seized in is to just smash them off with a hammer and prybar. Drill new holes and redo your wiring. DO NOT USE SCOTCH-LOCKS!!! These are not weather tight and will corrode the wire in no time!

 

The lights I replaced mine with are United Pacific brand and were only about $7 a piece. And you might get a little discount if you buy several at once.

 

When you put them back together, use stainless screws and put anti-seize on them, that will help keep them from being stuck next time.
