How would I go about wiring a third Piaa 520 light?

[gkatmar]

I just installed two Piaa 520 driving lights on my grill guard and I was thinking a third one in the middle would look pretty good. How would I go about wiring one more? Also, does anyone know how I can purchase just one Piaa 520 light? Thanks

Depending on how you wired the first two you could just splice a power and ground pigtail into your existing circuit and it would come on with the other two lights. The big thing to remember here is that I think the 520's come with an 85W bulb, these bulbs draw a little over 7 amps each so adding a third would increase your static load from 14.16 amps to 21.25 amps. This is a pretty significant amount of power and could require you to increase the size fuse you are using for the circuit and the size of the wire that you are using to power the lamps. You should also take a look at the size of the relay you're using; most quality lamp kits come with a 40 amp relay which will handle the added lamp just fine but some companies will save .02357 cents per kit and ship a 20 amp relay. This is fine for the original two lamps but wouldn't last under the added load.


Best of luck!
