Question:
We have a 2024 Flagstaff fifth wheel with Gustafson GSD5590 Textured Black Dinette light fixture. The bulb is not bright enough to do anything at the table besides eat. It is 3500K, 1W LED w/E15d bayonet base. Can we put a stronger bulb in that fixture and do you carry one? Just got a Jackrabbit tonneau from you. Great service.

Hey David, thanks for reaching out!
The Gustafson 12V RV LED Ceiling Light w/ Open Frame # GUS47ZR (GSD5590) does look like it comes with a pretty dim light, but you can definitely swap that out for something brighter no problem. According to my research the 1004/1076 LED Bulb # DI45VR will fit and is rated for 210 Lumens while still sitting at that 3500K color so you should just be getting a brighter bulb out of this kit.
Check out the attached video where we install the bulb in an RV and let me know what you think!

We did get a little bit brighter bulb, 3500K x 2.7w. Not great but better.
