Led light bar added to hi-beam lights?
Just wondering if anyone has attempted to hook up a small set of LEDs to their high beam light for that little extra light? If so will it cause any flicking or code to come up?

If you make your connections properly, this can be done without any flickering. I have a pair of Rigid Dually Hyperspots wired up to do exactly what you're asking. The aftermarket LED lights should have their own power supply and be controlled by a relay to avoid overloading your stock high beam circuit. DO NOT USE THE STOCK CIRCUIT TO POWER AFTERMARKET LIGHTS. Splice your high beam power wire and use that as the control wire to a relay. Pull fused power from the battery for your relay. Then, whenever you turn your high beams on, the aftermarket lights will come on as well.
Just a tip, I ran my high beam spliced wire into the cab to a switch, then to the relay. That way, for inspections and such, I can turn the switch off and my high beams will come on by themselves. Just gives you a little extra control in case you don't want your aftermarket lights on for any reason.
If you need any more help, or a wiring diagram explaining how to do this, just let me know.

I guess what I am wondering is:
1)Do you know which wire is the high beam wire on my truck?
2) where do I tie the wire connected to the high beam wire into the above assembly?
3) I assume no need for a fuse on the wire from highbeam wire to control source wire as the lights will be fed with power directly from battery when relay connects circuit from pin 30 to 87 in relay?
Thanks!

If you're able to can you send me a wiring diagram or post one into this thread? This is exactly what I am looking to do with my 2012 f150. I have a pair of black oak led cubes (like rigid d2) . They came with a wiring harness including a relay and fused positive battery terminal connector. It also came with a lighted rocker switch (on and off) with three wires going into the back of the switch.
I guess what I am wondering is:
1)Do you know which wire is the high beam wire on my truck?
2) where do I tie the wire connected to the high beam wire into the above assembly?
3) I assume no need for a fuse on the wire from highbeam wire to control source wire as the lights will be fed with power directly from battery when relay connects circuit from pin 30 to 87 in relay?
Thanks!

1)Do you know which wire is the high beam wire on my truck?
I went to the back of the passenger headlight with a test light to determine which wire was power for the high beams. If you don't have a test light and plan on doing your own wiring, it's worth picking one up. They're cheap and can be very useful.
2) where do I tie the wire connected to the high beam wire into the above assembly?
Tie the high beam wire into the switch, then the switch to the relay. If it's a pre-made harness, just make sure you know which wire is going where. A lot of pre-made harnesses aren't set up for this type of application and some use jumper wires at the relay.
3) I assume no need for a fuse on the wire from highbeam wire to control source wire as the lights will be fed with power directly from battery when relay connects circuit from pin 30 to 87 in relay?
Correct, no need for a fuse from the headlight wire as that circuit is already fuse protected. That wire will only trigger the relay so the added draw is extremely small. Also correct on how the LEDs will get their power.

No problem. I'll attach it.

I did kinda the same thing.
I installed a relay and 2 diode things, so my hi beams closes a relay with separate power for my fogs. separate circuit / 20 amp fuse. wont overload the hi beam fuses. stock fogs are 45w the new are 65w. I'm using Philips crystal vision ultras 9005 lo, h 11? hi and h11? fogs
hi beams are 6 bulbs lit and low is w/wo fogs. (2 or 4 bulbs)

+1 for wiring in light bars to the high beams. Very convenient and effective for flashing oncoming traffic during the day. I did this with 3x 30" bars behind my grille. If I need to have only the truck high beams on, I can yank the fuses for the relays.

I read somewhere that taking power from the LED high beam headlight wire to trigger a relay may draw too much current and shut off the driver circuit from the BCM to the headlight. Has anyone tried this with a 2017 f150 with LED headlights? Or is this false?
If true...would using a 3 volt relay(with free wheeling diode) drawing 6 mA in series with a 1500 ohm resister which drops the other 9 volts perhaps do the trick? This relay can then be used to power up a larger relay to power a light bar. Any techies wanna a bite?
