Default Headlight issues

I searched and searched and found kind of similar problems but not exact so here it goes.... I have an 04 wrx and I have had a Kaixen low beam HID kit for about 2 1/2 years now and have never had a single problem...but lately when I am driving down the road with no bumps or anything the low beams will cut out, only for a second or two and then they turn right back on....but when they do cut out I can hear the relay click. does this sound like a bad switch, loose connection in the switch, bad relay? I need some help on this one because driving down the road at night and ur lights cut out on ya is no good at all...

check all of your connections between everything
they could just be bumping loose on the road

Problems like this are very typical of HID kits. Reliability is not one of their greatest qualities, come to think of it I can't think of one good quality they have. Consider yourself lucky that you got 2.5 years of trouble free operation out of them. It could be much worse. They could have caught on fire.

Any way, if it is not a loose connection, the ballast on the one side is likely going bad or the amperage surge during start up has damaged one of your car's connectors, wiring, switches, or relays.

Check all the connectors on that side. Then if you don't find any obvious problems, swap ballasts from side to side. If the problem moves, it is likely the ballast. If not, something has probably melted on your car. HIDs draw a quick surge of up to 20 amps when starting up. The stock wiring system is designed for about 5 amps. This added current can easily damage something if the HID system is not separately relayed.

Well the problem isn't localized into one light or the other...it is in both... so switching ballasts isn't going to help me. I will check all of my connections in the morning but if your lights arent switched on when you start the car there shouldn't be any draw whatsoever correct? because my switch is always off when i shut off/turn on the car for the very reason of the power draw.

When HID lamps start up they draw more current not when you start the car. When the lights do that quick little flicker when you first turn them on that is what they are doing. Cheapo aftermarket HID ballasts draw a lot more than good OEM ones which makes the problem worse. STis that have OEM HIDs use a 10 or 12 gauge wire to power the ballasts because of this problem. Your low beam wiring is probably 18 or so gauge. It simply can't handle that kind of current for very long.


EDIT: If both sides are doing it at the same time it is more than likely your cars headlamp wiring system.

If there is one relay for both low beams, it might be bad.
A looose connection that effects both lights could be the cause.
At start-up HIDs have high resistance. A high voltage is needed to
start a current flowing. As the resistance drops, so does the voltage.
HIDs ues 20 watts less power per side. Standard wiring should be good.

well there's a left headlight relay and a right headlight relay it turns out and the chances of both being bad is very slim. still diagnosing....any more help would be much appreciated.

Try spraying the stalk switch with RadioShack Contact cleaner.

On 04s the low beam doesn't ground through the H/L selector switch like it does on 02-03s. So that won't be the problem. The ground goes through the DRL relay and then straight to ground.

Checking the DRL relay would be a good place to start checking for bad parts.

I have to question if that is really the case. It may be correct but if the problem reoccurs I recommend you check the control portion of the relay circuit. You stated you heard the relays click so that sounds suspicious to me. It may be the switch is intermittent.

well it wasnt the actual relay under the hood for the headlights...it was simply the DRL delay relay behind the glove box that clicks every time u turn ur lights on or off...so regardless of the bad battery, that relay will click every time.

I am having a very similar problem except I'm NOT hearing any relay's click and all my lows beams are remaining on ALL the time. My drl's are disconnected since I had HID's. I had a problem with someone trying to check my ABS light and jumping the connector now my headlights won't work.

Can someone tell me which relay is the drl relay behind the glove box? I have 2 blue that are the same, a black one with 5 pins, and another black box that says 15m on it. I think its a timer but not sure. This is an 04 by the way. Thanks for the help.

It's definitely a loose connection. In fact, I'll go as far as to say you're set-up isn't grounded properly.
