I can't find the answer through the search engine and I haven't tried to open up my lamps to see yet.
If one goes out, I have to replace the whole thing? Or can I just replace the little bulb inside?

Thanks,
Leigh

 

You mean the highbeam/lowbeam on the headlight?

 

No, the passing lamp bulbs.

 

The lamps don't come with the bulbs and there are several choices. You'll have to open them up and see what's in there. There are both sealed beam and bulb type available for the passing lamps.
