Tapping Into Fog Lights for LED Light Bar
Hey everyone,
I am looking for some assistance with tapping into my fog lights for installing a dual row 20 inch LED light bar. The specs are 40 3W LEDs and will have a light output of 7,000 lumens. I believe it has a 20 amp draw as it has a relay marking such. I have switched out my stock fog lights to led which draw less. I am looking into using a positap (scotch lock but better) to simplify and allow me to have them turn on with my fog lights. I see that the fog lights are connected to a control module and not a fuse. I don't want to overload the module and also ensure the wires can handle the draw. As a disclaimer I have done a search and haven't found anything.

Pulling power from the fog light harness may over power the circuit and cause issues down the line.

W/V=A so the bar adds 10A nominal, probably a bit less. While using a relay is always preferable (and more work), if the difference in amps between halogen (supposedly) and LED fog lamps is in that neighborhood, you should be OK with a direct tap. (Disclaimer - I am not an electrical engineer.)

So you plan on driving with the light bar on blinding oncoming traffic?

llangarica,
Thanks for the quick reply. So, I can just cut the supplied harness that has the switch and just use that wire to tap into the fog light and that should act as the switch?

Doyall,
Thank you, lol I'm no electrician either. I tried to make the conversion and thought it was 10 amp but was not sure what the module can handle as they are not marked. Thanks for your assistance.

RL1990,
Good job on jumping to conclusions. I'm going to let you in on some cool features on F150's and all other current motor vehicles. They have a factory switch which lets you turn the FOG lights on and off, ya I know really cool feature. Also, for jumping to conclusions and being helpful my setup also lets me adjust my light bar which I have angled down... One more little point if your not going to be helpful leave the trolling to reddit.
