Review on LASFIT Red 1157 2057 2357 7528 BAY15D LED Bulbs - Polarity Free, Super Bright High Power Brake, Tail, and Turn Signal Lights, Brilliant, Pack of 2 by Shane Black

I bought Phillips, LASFIT and Sylvania 1157 tail/brake light bulbs and compared them to my 1998 car's tail light reflector which was rated for P21W or 1157 bulbs which are fully reflective design and they were very dim in both taillight and brake light modes. Lightbulbs were so much brighter than each other that they seemed like a worthless novelty. However, they are better than the modified Vision-X brand LED bulbs that I bought in 2011. The LASFIT 1157 lamps, whose LED emitters face the reflectors, directed sideways and obliquely backwards, are much brighter than the Philips Vision. The reflected light is not as bright as that from an incandescent bulb, but there is a spot of more intense direct light from the rear-facing emitters. Sylvania ZEVO is a fully reflective design. It produces significantly more reflected light than LASFIT and slightly more than an incandescent lamp. There is a dark spot from the radiator, but it is surrounded by far more light than any other bulb produced. The benefit of using reflectors over direct light is more even light distribution and no hot spots that could dazzle or bother other drivers. Lightbulbs. Benefits of LEDs: - Lower power consumption, which is of paramount importance when leaving the headlights on without the motor and alternator to keep the battery charged. - faster brake light (no delay in heating the filament). - longer life (the lamp is less likely to fail due to filament fatigue or vibration damage) and longer intervals between lamp replacements. After evaluating three brands of 1157, I decided to buy Sylvania ZEVO for other lamps (mainly 1156) on this vehicle.
