Fuse for RI lights

[Jarek]

Installing two Rigid Industries 4" E2 hyperspots in the lower grille on my 2014 Raptor. Will be wired to AUX 2 that is protected by a JCASE low profile fuse. Combined draw of these lights is only 5.8 amps. Can't find a fuse of this type lower than 20 amps. Any advice?

I'm not much of a wiring expert... so I'll ping Noah for you @The Car Stereo Company

Why do you have a fuse? The factory switches are already relayed and fused

He is referring to the factory fuse and wanting to swap it for one rated closer to the current requirements of his lights for better protection.

I can be helpful sometimes.

the fuse is to protect the line against a short. it really has no value regarding the lights, except that the amperage rating must exceed the current draw of the lights. 20amps for those lights will be fine. the amperage of the fuse is low enough, that if you had a wiring fault before the fuse, it will blow and break connection. dont worry about trying to find a smaller fuse.

OK that sounds good. For my better understanding of the matter: if there is a short in wiring and the fuse blows when current reaches 20 amps, won't the lights be exposed to that current and suffer damage?

 

[Jarek]

As I thought more about it, that was a silly question. Current will flow through the short back to ground blowing the fuse. Will never reach the lights. Thanks for advice

you still run the risk of sending current to the lights, but as long as you insulate your connections, you will be fine

20 amp is the smallest available in that style fuse. I talked to Rigid tech support when I installed my 20" bar because there was conflicting information in the literature and what actually came with the lights as far as fuse sizing and he told me that the lights have under and over current protection built in so size the fuse for the wiring.
