for left indicator, push it down, for right indicator push it up; same as you turn your signal, the only thing is, you need to push it a little bit further. Good luck
was thinking of adding relay for e30 headlamps. but does it really make different cus i belive the current to the e30 headlamp are direct from the relays.
Your objective is to get a brighter headlamp. The only way is HID. No other way that I know.
Beware. I used to add a relay to my previous Jap car and upgrade the bulb to 100 watt. It serve my objective (to get a brighter headlamp) but it did melt some part of the wiring. Luckily the whole car not on fire
