Review on 💡 Ultra Bright iBrightstar BAY15D LED Bulbs 1157 2057 2357 7528 - Tail Brake Lights Replacement with Brilliant Red Glow, 9-30V by Mike Starling

I installed the red version of these 1157 LED bulbs in the taillights of a 1960's classic car where they are used for parking lights and brake lights. One problem many people have with these dual function bulbs is that the brake lights are not significantly brighter than the parking lights. This lamp does not have this problem. The parking light illumination is much brighter than the bulb it replaces and the brake light is significantly brighter than the parking light. People will easily notice that you applied the brake when the parking lights are on. I haven't had any issues with flickering lightbulbs either. My classic car uses an alternator, not an alternator, so the voltage will vary between 12 and 16 volts depending on engine speed, but these bulbs maintain the same brightness over this voltage range. I am very satisfied and will consider using them on some of my other older vehicles.
