Relay Question

[MadScotsMan]

I am finally getting around to installing my Bosch 180's on the Exploder. These have 100w bulbs and I was wondering what would be the minimum amps for the relay?
Thanks!

Watts/Volts = Amps

so = 200 Watts/12V = 16.7A As such a 20A relay would be the minimum size to get... I would pickup a 30A as they are built slightly better and have extra capacity for any future lighting changes you may add down the road.

A belated "thank you" DeRocha!
