Can I run 4 Hellas off one relay and switch?
I already have a relay wired up that used to run some fog lights that got tore off while wheeling. I want to put 4 Hella 500s up on my Yak Rack and was wondering if this can be done off just one switch and relay? I hope so I'm running out of places to mount switches and relays and getting tired of routing wiring.

go for it. I have all 4 of my hellas on one relay and switch. works fine. Just check and see if the fuse you have in there will handle all the lights, also look at the size of the relay.

Dunno what the current draw of the Hellas is, but if it is more than 7½ amps (or 90watts) per light you should use two relays (assuming standard 30A relays). Just trigger two relays off the same switch if necessary.

I have 2 Hella 500s and 4 Hella optix all are 55w and the are all on the same switch. I used 10 guage wire and used a heavy duty fuse (40) and holder. The wires never get hot and is connected directly to an Optima

remember, calculate amps by:
amp = total watts / 12
so 55 x 6 = 330 watts
330 /12 = 27.5
while it's still under the 30 amp rating of a standard bosch type relay, sure you wanna chance it?

If in doubt, you could always use one of these:
Cole-Hersee continuous duty solenoid. p/n 24059 rated at 85 amps continuous current. This is NOT a Ford starter solenoid but is very similar in construction. I currently have three of these doing various things.
