How to fix an older 12-v flourescent light?

One of the 12v flourescent lamps that I'm sure came with the boat in 1979 no longer works. I don't see where it uses a plug-in ballast, so I don't know what to do to fix it. I'm sure it must be cheaper to repair than to replace.
Does anyone know to id what part is bad, and how to replace it if it's obsolete?
Thanks.

Re: How to fix an older 12-v flourescent light?

If it is a 2 light fixture the ballast is typically located between the tubes under a metal cover. You might also be able to see a little silver canister. That is the ignitor and is prone to failure. . Finding parts is a hassle. Maybe it's time to replace with LED. If you like the housing a little led strip can work wonders, and it's natively 12 volt (most of the time)

It belongs in your pile of old useless stuff



And replaced with something that will work well,save all kinds of electric use while lighting the boat MUCH BETTER

We have installed LED strips and square fittings (4 elements) into old fluorescent figures with great success. All I used from the figure was the casing, lens, and switch. Much better light and much better power usage.

Ditto the other posters' advice to ditch the fluorescent tubes. Look at Marinebeam.com for some good tube replacement options (if you're willing to modify the fixture to remove the ballast) and fixture replacement options (if you're not).

It could be the switch has oxidized. Switch it 100 times and see if it starts working.

Regards,
Brad

Buy some 12 volt LED rolls on Ebay or at autozone. Connect to the switch and use the adhesive back to stick it to the metal.

+1 on going LED, but here are replacement parts...http://www.altestore.com/mmsolar/oth...t_lighting.pdf

I would verify that the problem is not power or switch related first. And, it could even be a bad bulb.

That's close to what I was going to say. Do what I did. Yank it out, throw it away, and put in LED lighting where it was.

I am working feverishly toward my goal of having nothing but LED lights on my boat. With battery power, LEDs just make sense.

Definitely LED. I am in the process of converting all my Alpenglows to LED. Much cheaper to DIY than to have them do it. Only 2 left but I will likely wait to do this as a project after we leave.
