Trailer lights (inside & outside)

[AZdriver_54]

Is there a list of the different bulbs that are used on the trailer? Want spares for emergencies and also want to upgrade to LEDs.

Thanks for any help, in advance.

Nope, there's no list that I've ever seen. Every trailer model is different and every model year uses different "low bid components" so almost every trailer will be different.

Typically most interior incandescent bulbs are 921 and all running lights, tail lights, brake lights differ with each brand of light used. However many newer trailers have "ever-changing" LED fixtures, often several different styles in the same model year.

It would be best to do a physical inventory of what is installed on your trailer and buy a few replacement bulbs that you know will fit your application.

Here is what I bought to change the 921 bulbs to led:
