Popular for price, colors, and availability?
I think most people get Nokya replacements for high beams because they come in yellow. They like the look & apparently is JDM correct. If you pull the DRL fuse and just have the bulb sitting there the reflector bowl makes the whole area look that color. Looks "cool" even when they are off.
I'm running Nokya Arctic White's as my DRL's cause I got a good price on them and they were available when another company was sold out. Got em through Xenon Depot/KBcarstuff. One of the vendors on here. Really good company, I definitely recommend ordering through them if you want to get some.
