Trouble shooting problem with docking lights

[cawood1]

Good morning, I have an issue with the docking lights on my 05" Tiffin Phaeton. Only the front driver side DL works. The other three are not working... I have turn on the switch and tried to see if I am getting voltage to them but no luck. Is there more than one fuse/bracket I need to check???

I'm betting burned out bulbs or rusted bulb contacts. If one works and the others don't that covers the fuse (they are on the same circuit). You can remove them by unscrewing the locking ring and unplugging the unit. You should be able to disassemble the light but if they are completely sealed, the Tiffin Parts Dept. has new ones.
