Review on 🔆 Wiseshine 1004 LED Bulb DC9-30V, 3-Year Quality Assurance (Pack of 4), BA15D 11SMD 5630 - Pure White by Richard Counts

I bought these hoping that they would be brighter than the standard tungsten bulbs that were installed in my bike's turn signals, but I was disappointed to find that the LED bulbs were as bright as the standard bulbs . To the seller's credit, they never claimed great brightness. Light output is decent as most reflectors are designed for a thin strip of light emitting tungsten and these LEDs are arranged in a ring at the same height as the strip of tungsten. It's still a little less even than a standard bulb, likely due to the imperfect mains supply that LEDs try to emulate. For turn signals, there are not many reasons to buy these lamps. The turn signals themselves don't use much power and aren't always on, so they somewhat negate the benefits of high efficiency and long lifespan of LEDs. This, combined with an equal or slightly worse radiation pattern, makes LED bulbs a net cheat in my eyes. However, the product works as promised, hence 3 stars.
