I have a UCC cobra. I purchased the 1157 LED bulbs for the two front maker/blinkers in amber and 4 of the 1157 LED's for the rear blinkers/brake lights. All the bulbs came from super bright LED's. When I put all the LED's in, everything works as expected except the blinker don't blink in front or rear. I get a steady light. I ran through numerous scenarios with them and changed bulbs and such and this is what I discovered. As long as I have one of the original incandescent bulbs in on one side, everything works including the blinker. I can put it in the front marker or one of the rear tail lights (have the double round) and it all works. After doing some reading, it seems as though I need a flasher relay or resistor due to the LED's not pulling enough resistance to get the blinkers to work with all the LED's in. Hoping someone can help me out with this and send me in the right direction to get them all working. Thanks.
