As for LED strip lights, IMHO, It's a safety that protects motorcycle rider from getting "T-Boned" by cars. Because some motorcycle had no reflectors on side (some are customized or removed) and in dark, some driver can't really see ahead of them because they may be color blind or their eye don't adjust to see at night well.. With LED lights lit on engine, drivers can see it so clearly. I would recommend White, Blue, Red, Yellow, and Green LED light rather than Purple LED. Purple LED don't shine as brightly as any other color LEDs.
I was planning on putting Blue LED strip light under gas tank in the future. It's not expensive, you can find it at Cycle Gear, Advanced Auto Parts and several places that sells motorcycle/automotive parts.
I would install switch or "photoelectric" switch so when it gets dark, I just simply turn on LED or turn on itself.
I also wanted to swap out incandescent Brake lamp for LED brake lamp. I would have to find one that have Red in center and White around or upward for license plate. Or use small "pod" of White LED for license plate. Because #1, it lasts almost forever, #2, less worry about getting rear ended by cars if incandescent brake lamp burned out. (Hey!!! remmy that MOST motorcycles have only one incandescent brake/parking lamp!!!! so when it burns out, wish you luck!!)
I've read about DOT issue with LED brake lamp couple years ago. They said that it's not safe to use it because under direct sunlight, sun outshines LED lamps cuz it uses ordinary high brightness LED lamps, not Luxeon.. But in fact are that many vehicles and trucks are using LED brake lamps. IMHO, its safe now cuz it use Luxeon LED probably 2 or 5 watts LED and are very bright which can be seen under direct sunlight.
LED brake lamp consist two parts of electrical wiring, It uses two resistors, for example 100 ohm for brake light, 200 or 300 ohm for parking light.. All wired to same group of LEDs, parking light would shine low but when brake being used, 100 ohm overrides parking light.
BUT, there are other LED brake lamp that have Luxeon group and High brightness group, Luxeon LED used for braking, High brightness used for parking. Make sense?
I ever wonder will they be using 5 or 8 watts modular Luxeon LED for motorcycle headlight? It's so damn bright and powerful, equivalent or more than Halogen lamp. . It is usually for high powered tactile flashlight which cost $200 and up. (If you use full power mode on flashlight, it'll use up battery in 15 min, just FYI)
For flashlight :topic:
