73 Int. Overhead Lights-Complete Replacement

1. I am sure someone has already cracked this nut and there are probably some really good threads on this subject, but I am not really finding anything. Anything you can suggest would be helpful.

2. I have a 73 31' Sovereign. My overhead interior lenses are all stained and aged. They need replacing. Also, most of the bulb sockets are developing an occasional short. It seems that I constantly have to take out the bulb, look for a burned filament-check for continuity with an Ohmmeter, etc. then get some sandpaper going on the socket contact to get things lit up again. So far, I have replace 2 of the 4 ea , 3 way switches (@ 7.50ea). Even when they all work-they:
-generate a lot of heat
-eat bulbs
-draw a lot of Amps-for what you get
-Look stained and draw bugs to die in the lenses.

3. I am looking for a complete retrofit solution using flourescents or LEDs. I want to do away with the lenses, install new, more efficient component in all 4 locations. I have considered Thin-Lite, etc. Any pics, part numbers or vendor sources would be great.

4. I hearby promise to carefully document and post my results for all to criticise and enjoy.

Trevis

I replaced the covers with new and used the guts out of a thinline to replace the bulbs. Others have used the new high output leds to good effect.

I just spent $280 for 11 fluorescent fixtures on Ebay. I hope I can fabricate a decent looking solution.

Rivet A Solution I Like

Royce did an excellent job of building LED lights for his Minuet. I plan on adapting the information found in http://www.airforums.com/forums/f447...ign-40936.html myself.

Once again, kudos to Royce!

Thumbs up Wow

I am impressed.
You are correct the old original setup is a constant weak link in the 70s era trailers. Your solution gives us hope.

Are the backing plates Aluminum ? Did you have them bent (folded) at a sheet metal shop? I am assuming they are one piece. Did you drill the holes or they?
If shop made, what is amount of labor for such a job?

Tell us more about the fixtures. Is there any manufacturer data on them?
Made in USA?
Do the bulbs look like you can easily get replacements? What diameter are the tubes and are they the twin prong or single prong ends?

How much more light do you think you are getting?
Any negatives in your opinion on the new setup?

Oh does anyone know if a Fantastic fan could go above such a setup?

Thanks

Fluorescent Lights

I used mill finish aluminum (.062). It probably was a little thicker than needed. My buddy bent it in a metal brake but it is about a 5 minute job for a metal shop. Some .040 or .050 should work good and be a little easier to work with. I sanded it with some fine grit and a stripping pad guided with a speed square to ge the brushed finish.

No markings on the lights-just generic made in China. Thin-lite brand would work fine, they would just be more expensive. They have twin prongs and are dual tube-8 watts each for 16 watts total.

The lights came from R and P Carriages Trailer Sales, Service, Parts and Rentals
