What kind of bulbs were installed, and why did the bodyshop need to install new headlights in the first place?

GG @thorny chasm, you just advanced to level 5! Chat more to level up and earn top roles!

not sure about the bulbs used but they do not match

#

also replaced the bumper

fickle trout
#

Can you remove the passenger side headlight bulb and take a photo of it for me?

#

Or is it inaccessible?

thorny chasm
#

it will take a while to do that

#

i figured if anyone knows if this singular flicker is a telltale sign of a specific cause then it would be worth asking

#

otherwise i would probabaly have to tear it apart and diagnose like you said

fickle trout
#

Lemme see

I'm gonna do a lil research.

thorny chasm
#

i would have to remove the left side air filter housing

What year is your g?

fuses, connections, and grounds are all possible i feel

fickle trout
#

I'm pretty sure the ballast is either defective, or they reused the one from the damaged light.

thorny chasm
#

oh yeah that thing

#

may i ask what points you towards that component rather than wiring?

fickle trout
#

Because the headlamp ground is shared by all of these components

#

And also, the flickering/blinking reads ballast

thorny chasm
#

i see…

fickle trout
#

Usually an intermittent power connection won't be symptomatic while the car is sitting still, as well

thorny chasm
#

i’ll be sure it check it out. it’s not a huge issue rn but might it eventually just give out completely?

fickle trout
#

The usual failure mode is that they turn on when you turn on the headlamps, and then they shut right back off.

#

Whichever one is faulty, that is

thorny chasm
#

yeah other one is fine

#

maybe this cooler hue one that’s flickering could be bc of the bad ballast? or do bad ballasts usually make the light turn more yellow as it says online

fickle trout
#

It's probably just because it's a different light temperature/bulb color

thorny chasm
#

oh ok

#

thanks a lot for ur help now i’ll now what to look for

fickle trout
#

If you have a multimeter, it would not hurt to check the red wire for full alternator voltage, of course.

#

And for ground resistance on the black wire.

thorny chasm
fickle trout
#

Yes. What I meant is check for 12-15v on the red wire.

thorny chasm
#

it leads me to believe they are the same bulb but for some reason they are just acting really weird

#

do you think i may need to get new ballasts for both?

#

are you even sure the bulbs are the same

#

there are aftermarket bulbs that are tinted to get it to be "more blue"

#

I don't recommend using those because it just makes it dimmer
