Relays for Brake & Reversing Lights

Should I use a relay for a single reversing light and brake lights?
Im not sure how many amps the switches are rated for.

Not needed imo.

21w a piece @ 13v is around 1.5A each.

Sierra's didn't use many relays and a reverse switch will easily handle the current.

Get led lights, they're the future, and the future is here!
Plus they only take something like 0.1 amps each, which is even better. Wiring can be thinner, smaller fuses etc

Thanks.
Thats good news as it saves me a couple of spaces in my relay box!

I've already bought the lights from the kit manufacturer (Sylva) so dont want to buy any more - already somewhat over budget!

Brake lights are not normally wired through a relay.
Reverse lights are normally only wired through relay on cars with automatic transmission.
