Hella 500ff fog light installation -- wiring question

[vicar]

I'm trying to wire in my hella fog lights. The directions the lights came with are useless. The directions I find online either don't have the colors/numbers I have or they don't do it the way I'd like to do it.

I'd like to wire the lights directly to a switch -- not through high beam or low beam headlights -- so I can turn them on separately. Does any one have any guidance? Has anyone done this?

Thanks for your help.

This is all you need to know:

Since you want full-time use, connect the switch leg to battery positive. (Either use an in-line fuse or connect to any full-time fused circuit such as DOME. Don't sweat the colors and numbers, think about what the wire goes to. If you meant the relay numbers are different, then you need to post some pics of what you have.

Thank you. One more question. I'm using this switch:

Amazon.com: Laser Backlit Green Rocker Switch FOG LIGHTS 20A 12V On/off LED Light: Automotive

It has a built in backlight. Does that change anything on your diagram?

Can you post Pictures of instal of the lights. I'm trying to figure out what I can use to replace the factory rectangle fogs on my 97 limited.

Slightly. From your link:

Upper light is ON when the switch is pressed UP. Lower LED is independent and can be wired to separate dash light circuit. Both LEDs have separate grounds.

Just wire the two grounds together and then take the wire to any ground point. Take the lower LED positive lead and connect it to any circuit that behaves as you want it to. I'd suggest the first green wire that you can find, such as the one to T1 of the dash rheostat (dimmer). That will give you an undimmed 12V+ that comes on with the dash lights, which is what you want for LED's. Then you can ignore the indicator light shown in my diagram.

2001 TR4 Hella fog light wiring. High beam wiring question.

Hi there. I have a question maybe you guys could help me out with an issue Iam having with my driving light install. I have performed the drl mod to disable my drl's. I have wired my lights w the supplied relay per the hella instructions. I tapped my left side high beam fuse, to be a trigger wire for my relay. My issue is, that everything works fine... Except when i turn my headlights off, the hella lights flicker when i turn the headlight switch off on the steering column. Iam Just curious if anyone can explain why the trigger wire I installed off my left high beam fuse is getting power briefly when I turn the headlights off? I appreciate your time and insight. Thanks in advance.

I just installed some hella 450s. No wiring for fog lights on my 97 Limited but I found existing holes under the bumper to mount them close to where the stock ones would have gone. They came with a three prong lighted toggle switch so I used an "add a fuse" with a 3 amp fuse running to the third clip on the switch. I put it inline with the parking lights so I get the lights on buzzer if I leave them on and I can't turn them on unless at least the parking lights are on.

Your install looks good! I like having mine wired into the high beams, one less switch to flip when you have oncoming traffic, just my preference. My issue is my lights flicker when I turn the headlights off. Just wondering why they are getting power briefly? I tapped through the Left High beam fuse under the hood. Thanks for your time everyone!

 

[wemslie97]

Not sure on that issue. Maybe make sure all your grounds are connected well?. Some residual power somewhere?

 

[wemslie97]

All I could come up with was a failing battery and/or alternator or Rectifier malfunctioning and possible over wattage for the system and/or a bulb issue. Are you using a relay? They can also go bad and cause flickering from what I understand. Hope this helps.

 

[SlickTR4]

Okay sounds good. I am running the hella relay that comes with the kitt. I will re check my connections and grounds. Thank you for your insight, I appreciate it.

No, his are FOG lights. Yours are DRIVING lights. Fog and high beams do not go well together.

Which lights flicker, the driving lights, the headlights, or the dash lights, or all the above? What happens if you just turn off the key?

 

[SlickTR4]

I appreciate your response. When the driving lights are switched on, I installed a toggle switch on the trigger wire to the relay... The driving lights will flicker when I turn my headlights from on to off. No dash lights or indicator's flickering either. They do not flicker when I turn the headlights on. The lights operate properly with the high beams and ect. I tapped my left hand high beam fuse for the trigger wire. The power has to be coming from it. I also have performed the DRL mod and have them disabled. Any thoughts on this is appreciated. Thank you for your time
