Spent all day yesterday, ( had surgery ) looking for a bulb with 1156 base, that had more than 10 Watts. There's not enough room for the regular size bulb for 1156. I was able to find a 14.5 watt bulb in the smaller size. At the very least, I hoping that this will slow down the blinkers to a usable rate. I only found one company that carries LED's with built in resistors. They fit 1156 & 1157 size. So no inline resistors, and all that. The cost is about $45.
