    Headlight upgrade 82 Cm450e

    After squinting at night too many times, I have decided to upgrade the dim stock headlight for a HID one.

    I currently purchased one on ebay: Motorcycle Headlight 7" H4 Bulb SEALED Beam Cafe Chopper Bobber Harley Honda | eBay

    I have already mocked it up on the bike and it will fit well but will this be too much wattage for the bike to handle?

    The bulb is a H4 55/60 watt and would be a huge upgrade from the stock. I am just wondering if I would have to modify anything electrical to make the headlight work or if it even will.

    It's not an HID.. that's a whole different style of headlamp. This is a halogen, and the 55/60 is an awful lot for your electrical system. There are only so many watts to go around. If you're hell bent on running one that bright, I'd go to LED on every other bulb, in the hopes of making up some of that wattage. That will require a solid state flasher relay. Then, I'd use two relays and a nice 12 gauge from the battery direct.
    This diagram is the correct wiring, just ignore that the high and low beam are separate bulbs.

    Vintage motorcycles are just like women. They're moody and mysterious, they require a lot of maintenance, and you want to ride them all.

    The charging system will handle the 55/60 bulb easily, been running that for 4 years now.

    Great, so it will!

    Will I need to do anything else or is it plug and play?

    I'm not familiar with the unit you ordered but I'd guess it'll be plug n play
