I have the TJM from bumper and I am ready to replace the 7" round fog lights with a LED light bar. I found one that I think will do the trick, however I am not sure if 126W is too much... I have a feeling I will need to up the fuse already in place for one that can handle more? Is this correct? I don't want to damage anything, the (LED light bar) appears to be a plug and play. The link to the light bar is below. Thank you in advance.

What amp fuse. I assume relayed factory switch? My bar is on a 20amp, but it's a single row. My guess is that it'll be fine. But you will find out pretty quickly.

 

@Dusty 1, that's what I was thinking..

 

126 Watts worth of LED's ........................ you'll 'burn' them to death with that lot

I'm sure the LR system will cope via a good relay, adequate wiring and quality switch to it but fuse it separately..................... just in case

PS. Quickly doing the calcs 126W at 12V it's only 10.5 amps therefore IMO I'd use a 15 or 20 amp fuse but ensure the wiring and relay is rated heavier than the max load.

 

I=P/V

126Watts / ~13Volts = ~9.7Amp draw

I think the factory aux light harness is rated for 15A. Leave the 15A fuse

 

Maybe I should just stick with the 7" lights I have.. In all honesty, my disco rarely see's non -pavement. My current lights have a classic look, I see all these LED bars on other trucks and I am wowed by the way they light up the road. Thank you for all the input thus far.

 

Definitely agree. The old school looks better, but will never preform nearly as well.
