Recommmended LED Replacement For 921 Incandescent Bulb
Updated 01/27/2026 | Published 08/24/2024
Question:
My friend has a StarCraft galaxy travel trailer with 921 incandescent bulbs for lighting. He wants to change to an LED light. Tried one product that wouldnt work. Had to force the new bulb in the socket and then after a bit the bulb would work its way out of the socket. Would you have a recommendation as to the type of bulb that would work in this application.

Hello Adam. We do offer some of the 921 bulbs in LED. For that I recommend the 921 LED Bulbs # ARC48FR. This comes with a pair of bulbs. I am not sure what bulbs you tried previously, but I can assure you that these are a suitable replacement for the 921 bulbs.

Hey Adam, how did the 921 LED bulbs work out in your StarCraft Galaxy trailer? It’d be great to know if they fit the sockets better this time. Your update could make it easier for others switching from incandescent bulbs.
