Are they flickering? Maybe you need new bulbs?

I had to reseat my rear connector to ensure the light connected correctly.

I was having problems with turn signal light.

Have you done the harness mod that involves trimming the tabs so it stays seated in the headlight?

Worked for me.

I'd assume you have inspected the headlight wires?

Cleaned the connectors with contact spray and the hand cleaned or inspected the female connectors on the headlight.

Also looked at the fuses for the headlights and turn signals.

I think your said it's happening on both headlights. Is that correct?

Did the flickering issue begin after you did the mod?

Or when you replaced the headlights.

thanks for the replies, however they are not flickering they just go off. no mod just get the check beam warning. i have clean it thoroughly. i have to physically unplug the connector to the bulb and it works fine again on both headlights . i don’t think it’s the connection from car to the headlight case but more from the connection to the actual bulb . i haven’t checked the fuse though

Have you checked the wiring harness? How does the insulation look? On my '06 S, the insulation had fallen off, and was causing that same issue. I bought a new harness, and no more problems.
