My neighbor has an 03 Ultra and needs a new headlight. Is it a bulb or sealed beam?

 

Take it apart and see. I recently replaced the headlight on my 01 Road King with a Sylvania something or the other white light from Autozone. Cost me about $27 and change but a whole lot brighter.

 

My 2000 Road Glide twin headlights run bulbs. Bought the Xenon replacements for around $8 for the pair on EBAY. They're much "whiter" than the "yellower" lights the bike came with.

 

Just look at the front of the headlight... it will say "sealed beam" in raised glass letters or it will have a center diffuser and it is not a sealed beam.
