Review on 🚴 SEALIGHT H4 9003 HB2 LED Motorcycle Bike Bulb, 6000K Xenon White - Enhanced Visibility and Style Upgrade for Two-Wheelers by Terrence Castillo

*Very satisfactory low beam; the high beam is superior to other LEDs, the light output is weaker than halogen (this can be a limitation of LEDs in general, since the geometry cannot replicate a 360-degree luminous film). **Pattern DOT Approved, Roadworthy*** Low and high beams do not turn on at the same time like some LEDs do. As you can see from the pictures, both the low and high beams use 12.5 watts. (0.95A at 13.2V) Bench temperature reached 180F maximum temperature (75F room temperature) and 96F maximum temperature (70F outside temperature) when installed in motorcycle headlight with rear hole (1"x 2") during movement. Installation is easy, especially with the ability to remove the rubber boot LED mounting plate (which most headlights have) to properly mount it to protect against water and dust. There are no adjustment options as it seems to correctly replicate the position of the filaments of a halogen lamp. In terms of lighting capabilities, this product offers an improvement over the H4 halogen bulb, mainly for low beam. The drawing is correct, decently focused and lots of light. The high beam is better than other LEDs I've tried, but lacks the range of a halogen bulb. The pattern feels right, not too wide and not too high, but it doesn't extend forward as much as regular halogens. Undoubtedly it is usable and much better than other products like I said, but don't expect "strong projector beam". There is a newer version of this LED that I would like to test for high beam improvements. Have fun, be safe!
