Light flicker on 1st acceleration

[Mudeprived]

This is a strange one. The truck had a headlight flicker ever since I bought it. The headlights would flicker once after 3 seconds into the first acceleration and never again until next morning. I would back down my driveway onto the road and it doesn't do it but it does once I start moving forward.

It is not a huge deal to me but I am wondering what would cause a one time flicker in the headlights on acceleration?

Loose wire? I'd start checking at the bulbs, maybe an ez fix. :cowboy:

But it is kinda weird how it only does it once and at the exact same time every time. I changed the bulbs not that long ago and it did not change. I guess I will check the wiring.

Checked for a corroding connection. You could always see how many amps one side is drawing versus the other, to see if it is indeed a wiring issue.

ABS cycling once on startup. Its a couple seconds after you take your foot off the brakes while moving. (so, you could drive for a long time on the brakes and it wouldn't do it)

It happens for me just after I staring moving forward after backing out of the driveway.
