### ⭐⭐⭐⭐⭐ Bright and easy to install
*by M***L on August 8, 2025*

EXCELLENT! Sea light has never failed to impress me with their products, and this is no exception. PROS: - BRIGHT! - White light for improved visibility - designed to work perfectly with fixture reflectors CONS: - When turned on without the engine running, the heat sink fans can faintly be heard. I have no idea hot this is a negative trait, but I wanted to add at least one "con" and this is the only thing I can think of. INSTALLATION These headlights are no more difficult to install than a standard bulb. Be sure to use the included gloves, to avoid getting hand and skin oil on the LED surface. COMPATIBILITY Although the heat sink includes a tiny fan, the product description indicates these are designed to work in enclosed fixtures with the dust cap installed. I've had these installed in two cars for the past month and have seen no problems. Although the LEDs are mounted on the sides of the fixture, the reflectors built into the headlight housing still reflect light perfectly. The design adheres to the dimension informed of a regular incandescent bulb, and light reacts accordingly. I see no different in neither light pattern nor coverage for either high or low beam. (My cars require four of these lights: two for high beam, and tro for low beam.) YOU CAN'T GO WRONG WITH SEALIGHT!
