Review on 🚦 Everbrightt 10-Pack Turn Tail Signal Bulb S25 5050 1157 BAY15D White 27SMD LED Replacement Bulbs: High LUMS, Ideal for RVs, Campers, SUVs, and More! by Bryan Hill

took forever. Amazon says they were delivered in June but I only received them last week. Everything was ready, I bought several for my car, which I immediately received from Lumen. I have now used one on a friend's truck and when we put it in the brake light it didn't work, tried all ten bulbs and same problem. Put in the spare lumen I had and it worked. tried again later, only with a battery in the house and it worked by itself, hardly any difference in the brake light and rear light. The problem lies in a hidden passage in the light bulb. This allows current to flow from side to side, and if you have two light bulbs in parallel and one of them is this bulb and the other is an incandescent bulb, the brake light on that bulb will not light up. Also the light produced is not wearing if you look directly at them, they look bright but stand to the side even at night and the light hardly illuminates anything behind the car that is more than five meters away from the light source. there is just no power. I like the lumen ones much better, they use smaller Super Brite LEDs and fit a lot more in the bulb.
