LED Headlight Interference

[SubSonic]

I just purchased some H11 LED bulbs and replaced the halogen bulbs in my 2018 Tahoe projectors. Although the light output is decent and cutoff/beam pattern is good, I'm running in to an interesting issue that I wanted to see if anyone here had experience with.

These LED lights interfere with the back-up camera. The image becomes shaky and grainy when the lights are on and returns to normal when they are off. No other interference with radio or otherwise.

I've tried ferrite coils on the wires and even tin foiled the dust caps to attempt to diminish the interference, but with no luck.

Is anyone running LED headlight bulbs that don't cause interference--or have you experienced this issue?

What brand did you purchase?

 

[SubSonic]

They were some relatively inexpensive ones on amazon (Just over $30) called S6. I know they are causing the interference. But I was curious if something like the Morimotos from TRS would not cause the same. I don't really want to spend $120 to find out they do the same thing.

You may need to add in resistors. I have read a lot of people on other forums getting fast flashy or other interference from LED bulbs and adding in a resistor cures the problem. Same type used for the Esky tail lights - 50W 6ohms. I would dig in on the S6 forums first though.

On the headlights??? That will just dim them (by dropping the voltage to them).

I guess that I should ask, in series or parallel?

how are they connected? if thru the factory harness then you might try using relays instead that takes the load off the factory harness and fuse box and basically makes it a separate electrical system, very easy to do.

I believe he was talking about something like: https://www.amazon.com/gp/aw/d/B078X1JNYW/ref=cm_cr_arp_mb_bdcrb_top?ie=UTF8

Which is supposed to act as a resistor (to fool cars that care into thinking an incandescent is drawing full wattage) and an EMI filter—I may see if something like this solves my problem.

That’s actually how I am running my fogs and they have no interference. Only the headlights. So that may very well be a good option. Thanks.

I actually have experienced similar but minor blur in the back up camera when lights are on after adding LED plug and play. Not bad enough to bother me but noticeable. Paid $90 for mine. Don’t recall the brand.

For LED issues you should be using resistors much like the way they are used on the Escalade tail light installation.

For HID issues, I purchased these to stop the flickering: https://www.diodedynamics.com/canbus-anti-flicker-module-pair-connectors.html

I just upgraded to LED Headlights and Fogs two weeks ago and have no issue at all including what you are describing.

Both were plug and play without any additional capacitors or anything.

Hello subsonic. Glad you are pointing out this, our kits has been tested one of the best kits out there with no issues at all not even the ones you are having! Out kits are 100% plug and play and error free as well. You can buy ours which they also have a very good reputation and trustworthy reviews from real buyers here on the forum . Let me know if you need any help or have concerns . Thanks

Just wanted to update that this issue was solved by using different LED H11 bulbs, so obviously just a bad set with interference.

Mind sharing brand and source? I’m looking to get LED bulbs and don’t know which to go with.

Sure Can. Still no issue. Absolutely love them.
