I have a 1999 GoldWing 1500SE and my left low beam is out. Do I have to order H4 12V 45/45W from motorcycle supply/or shop or can I buy in auto parts store? I have downloaded the "how to replace" and I know it will take me a while to do and I'm trying to avoid taking to shop as it is almost 50 miles away and with cost of parts and labor I would attempt to do on my own. If low beam is not working, is there a way to check and see if something is loose or maybe a fuse or something else? I appreciate any and all help and suggestions I can get!
