Review on Blazer B430BLK 4 Inch Round Flange by Sean Maile

Good light for the money - defective bulbs in both units. Bought two of these lights. I checked both and found that the red wire (STOP - high brightness) had a short to ground. The brown wire (rear light - lower brightness) lights up. I removed the bulb and checked again. There is no short circuit in the lines. I checked the light bulb - it has a short circuit to the case on one of the contacts. EXACTLY the same on the second block. You must have a bad batch of 1157 lamps (probably from China). So now I have to order a set of 1157 and spend another $4.50. Called customer service - they were very nice BUT didn't have or offer replacement bulbs.
