I want to change the color and the type of led bulb thats in the spyder projector headlights. Since I have two that are blown and they are not that bright, I thought about just switching them out. I looked at the superbrightled website to buy some but not sure which ones will fit. I pulled one out of the spyder headlight and it looks like a wled-x 194 type bulb. Does anyone know for sure? Also, can that single bulb type (wled-x) be switched out with a wled-4x, wled-5x, etc?
