I have a ‘75 ST90 and I am tired of the head light dimming when brake light or turn signals are used. I am looking to change the headlight and tail/brake light to led. I have the replaceable bulb headlight but not having much luck finding an led for it. Have rear lights coming. I ordered some H4 6V leds but the base is waaaay too big. Anyone know of a plug in led for it?
