my HID headlights are real bright when i first turn my truck on. then after a short while they will go dimmer. what could the problem be. any help would be greatly appreciated.

 

hids flash bright real fast then go dim and start heating up to maximum brightness. do they stay dim? it typically takes about 15 seconds for them to heat up and get bright.

 

yeah they warm up and get bright. but then after they just flicker to dim and stay that way

 

what kind of hids do you have

 

i got the bi xenon 6000k from xenonlink.com

 

yeah i know what you mean mine do the same thing they go through the startup process and then they dim out just the slightest bit never thought anything of it there still bright i figure they get back to the normal brightness just takes some time so you dont notice it not like when they go dim

i dunno maybe i just have a junk kit

 

i dont think mine get back brighter. i didnt think i bought a crappy kit. for 150 dollars it shouldnt do this

 

This is what mine have been doing for the past +2 years (minus the 8000k color).

That's how most kits I've seen work (with some kits warming up faster than others). If yours are dimming I'd think there is something wrong with them? Contact your seller and see what they have to say.

 

sometimes, you have to upgrade the fuse tothe headlights at least 5 more amps, i have 12k on the navigator 6k on the f-150 and 8k on the impala, i upgraded the fuse on all of them by 5amps, and they are bright as hell imo.. illl make videos later tonight..

 

The fuse to the ballast shouldnt matter. If its not blowing your current fuse then it obviously isnt wanting to pull more amperage.

Either your bulbs are going bad or the ballasts are not producing enough voltage after ignition to keep the bulbs fully lit. (sounds more like the latter)
Both problems related to your kit, i would contact the seller.

I had a ton of problems with my xenon-link kit. A year after i purchased it, of the four ballasts i got, only one works to this day and finally just did different branded bulbs. 4 ballasts and five bulbs from them (head and fog kit) and only two (one fog one headlight) bulbs still work and only ONE ballast still functions normally. Just my personal experience. See if you can get some money back and ditch the crap HID kits.
Look up retrofit projectors on this site and do it right.

 

Bad kit.

 

yeah i guess its just a crappy kit. im gonna do the retrofit when i get some money. its hard being a college kid.

 

maybe try some hid capacitors, i put two on each and it solved my flickering problems

 

where do i get those from?

 

Ever try googling it?
