Driving light bulb # for 07 ElectraGlide
 

I did a bit of research on what bulb is required on the 07 ElectraGlide driving/spot lights but got confused. I'm going to upgrade to a whiter and hopefully brighter light and need a bulb #.

I'm going to go with a different main headlight bulb such as the Piaa 70456 Xtreme White Plus H4 Anti-vibration and would like something similar.
