Headlight bulb H7

My bulb burnt out. I wanted to go with a brighter bulb,( not necessarily HID ) I called my local BMW dealer they strongly suggest staying with he stock bulb. They sited over heating and possibly melting plastic pieces. I was looking at several bulbs. It looks like the watts are the same (55w) but the brightness is higher. Should I go stock or brighter?????

Any and all input is welcome.

Did that with my bike, Silverstars ultra....lighting still sucks and you trade bulb life for some extra brightness. Not worth the $30.00 I paid for it, you can get an HID kit for not much more than that. That's the way I'm going, gotta see them Bambis at night.....!

I had to replace my bulb last week and I was looking at the different bulbs from Sylvania. They had a little chart on the back of the package that showed which bulb was brighter than the others. They had a little disclamer at the bottom that made my decision easy. It stated that bulbs lose their brightness over time and their brightness compairison was based on a new bulb at 100% lighting verse a bulb at 80% ... I laughed my ass off and grabbed the cheapest bulb.

Brighter bulbs at the same wattage won't cause grief. BMW service folks are used to people putting in higher wattage bulbs to get more light, sometimes at the expense of a burned connector. BMW likes to engineer things, and if a wire gauge will support 55 watts, but not 60, they'll figure they're good with that wire gauge. Also, 55 watt tungsten bulbs will put out less heat than 80 watt, so you may cause the plastic headlamp reflector and housing to distort.

As was pointed out, for the cost of two $30.00 bulbs you can get HID that uses less power (35 watts) and puts out more light.

DDM Tuning provides a good kit for motorcycles. Third on on that page (DDM 35W & 55W Single Motorcycle HID System) is the replacement for the H7 bulb used for the low beam. PIck 35W or 55W as what ever suits you ... they both put out more light than the H7 tungsten bulbs, even the pricey PIAA bulb (which is a bit brighter than the Sylvania's).

I'd recommend the 4500k or 5000k color temp unless you're looking for a bit more "style" in yellow (3000k) or blue (8000k+) Keep in mind that outside of the 4500-5000k range the amount of visible light tends to drop off.
