New light bulbs don't work!

Our sconces on the back wall light bulbs burned out. These lights work on the battery. I just can't get these light bulbs to work. Any suggestions? Thankyou

Both bulbs burned out at the same time? I would guess the bulbs are not the problem especially if you have replaced one or two and they don't work.

Check to see if you have 12V at the fixture(s) and the switches. Look at the fuse panel for a little red LED being illuminated under the fuse for the sconces. This appears to be more of a 12V supply problem. You can try moving one of the "dead" bulbs to another 12V light (on a different circuit that works) and ensure it is indeed "dead".

The way they place those sconces lights on exterior walls often create condensation on the back of the fixture. (Learned that early on from this forum) That condensation over time leads to switch failures. Both sconce lights above our bed failed within 3 years. Found replacement push button switches at Lowes.
Follow Carl's suggestion and verify 12v, if present jumpering the switch will verify if thats the problem.

It would extremely unusual for two light bulbs to burn out at the same time. When did you have two in your home to burn out together? Look for another problem.

How old is your trailer? I had to replace the push button switches on both my rear wall lights and both my bedside wall lights on my 2007.

Do you have any blown 12 vdc fuses? A red light on the fuse panel means that fuse is blown.

If no blown fuse, the next thing to do would be to take one of the fixtures off the wall and use a volt meter to see if there is voltage to the fixture. If you have a volt meter and know how to use it.

I recently helped a friend with an older Montana replace 5 of his switches. His lights haven't worked for years. We bought them on Amazon very inexpensive.
