Hi everyone,

I just swapped out my headlights to a custom set by JNC this weekend (who did a great job on them btw) and also put in new D2S Morimoto 5000K Xenon bulbs since my stockers were aging.

I drove around last night and both driver and passenger xenon bulbs were working great. I turned the car off which also turned the lights off but realized I wanted to quickly check the cutoff. I turned the headlights back on and noticed only the passenger side ignited. Tried again - same thing. Turned the lights off and let everything settle for 5 seconds, tried again but this time it worked. I checked the lights again before I went to bed and they fired up the 1st time. I checked things today after work and noticed the driver side didn't fire if I turned the lights on right after turning them off. Again, if I let everything settle for 5 seconds they both work.

I believe my battery may be on its way out but I don't think this would cause this intermittent headlight issue.

Possible bad headlight bulb, bad ignitor, bad ballast, just a quirky thing to deal with? Thanks in advance for your thoughts and opinions.

im having this same problem too on my passenger side.i replaced both ignitor, ballast and bulb but dont turn on right away if i turn it off only if i wait a couple of seconds

 

Good to know! Thanks. I don't think I ever tried turning them on right after they were off before swapping out the headlights so maybe they've always been this way? You've replaced all the components I listed as potential sources of the issue so I'm not sure why this would happen. Hopefully others will comment.

 

Anyone else experiencing this? I can replicate it by turning the headlights off then back on quickly. Happens 90% of the time and only on the driver side.

Thanks,
Jon
