Hi All, I've seen the threads detailing adding relays to the headlight circuit.
My question is what relay to use?

Thanks!

If you’re asking that, making your own relay kit (2 relays actually) may be difficult.
But buy you a Toyota light kit (find the thread on here). It’s a quality plug and play relay setup and you get free headlights. For cheaper than a quality relay setup from the classic car places.
Don’t buy an Amazon kit. They’re cheap. I bought one and it was not worth anything. Period.
