What amp relay should the headlights be on?
Your average high beam (for a normal headlight) is 55 or 65 watts. In a 12 V circuit, that’s less than 6 amps nominally. If you put in a 10 amp fuse, you should be ok. I have looked at some amperage vs wire diameter charts and 20 amps seems a bit too close to the 24 amp maximum for my comfort levels.
Do you need headlight relay?
Every so often, the question arises – should I add relays to my headlight wiring. The answer is yes! Power is conveyed from the power source (battery/alternator) to the lamps via the wires, connectors and switches. To ensure maximum power delivery, there should not be any power loss in the circuit.
What causes a headlight relay to go bad?
Bad Connection A headlight relay switch may malfunction due to a loose or faulty electrical connection to the coil, which generates a magnetic field when voltage is applied. The driver should check the wire connection and tighten it if loose, or replace it if corroded or otherwise damaged.

Where are the fuses on a Toyota RAV4?
Fuse box diagram (fuse layout), location, and assignment of fuses and relays Toyota RAV4 (XA40) (2012, 2013, 2014, 2015, 2016, 2017, 2018). The fuses are designed to blow before the entire wiring harness is damaged. If any of the electrical components do not operate, a fuse may have blown. If this happens, check and replace the fuses as necessary.
