Re: bulbs keep burning out
When you replace headlights in today's cars, DO NOT TOUCH THE GLASS OF THE BULB!. Handle the bulb only with the packing material the bulb ships in, or with a clean dry cloth.The oils in your skin will cause premature failure of the bulb.
Also, check the sockets (car side) carefully to make sure they are not burned.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Bad circuit board tail light asseblise connector pin to board poor connection or burned push in light bulb sockets
On my '93 Chevy PU the new ones went bad within months I repaired the original ones by soldering all connector pins to the board cleaned the sockets chipping out melted plastic been working for five years now.
Care must be taken to keep solder from preventing wire connector install while using enough that plugging it in will not break these delicate unions.
Required pulling them several times to Finnish repair successfully.
Very disappointed in replacement parts.
Blown fuse ,bad headlight switch,or wiring issue.
the tail lights have there own fuse and are powered through headlight switch. Do the front running lights come on? If none of them work, switch could be bad if front work and rears dont, check bulbs and power to them when lights are on
You only need to change the tail light fuse if it is blown. If you haven't checked it already, do that. Those stop/tail bulbs are 2 filament bulbs. One filament is for brake lights, and other filament is for the tail lights. So it is possible to have brake lights and no tails, if the filaments for the tail lights are burned out. But of course, it is unlikely that all the tail lights would be out and all the brake lights still work.
You may need a voltmeter to help solve the problem. It could be a problem in the headlight switch (a problem with the park light function), but is more likely a problem with the Lighting Control Module- or the Body Control Module-whichever your car is equipped with. GM first came out with the LCM, and a year or two later came out with the BCM. Both are mini-computers to control lighting and cabin functions. You would have to use a voltmeter and check things like power in and power out at the BCM of the park lights. You would thus need a wiring diagram to go along with the voltmeter. Those modules are located up under the dash-you can use google to see pictures of them, and maybe find locations.
Try replacing the relay switch. Check and see if you have a Relay for the headlights/lights for your vehicle... sometimes the relays can end up bent and corrosion can settle at times...not sure why, but its happened to me several times in different vehicles...good luck!
The relay has nothing to do with the tail lights, but replacing the switch sounds like a good idea. There's a nut holding it in place, see http://www.skandix.de/en/spare-parts/electrics/switches/switch-headlight/1027524/ to get an idea of the construction. And the price. This is not worth fiddling about unreliable workarounds... In addition, if fuses 15 and/or 16 burn frequently there might be a problem with the tail light cabling.
Try removing the bulbs from the rear tail lights you have one 2 bulb system shorting out, so one at a time remove the bulbs then replace the fuse and see which one is bad or just buy new bulbs and replace, also could be front running light blinker light. But sounds like brake light to ground threw bulb.
ok supaxang, could this solution be as simple as replace the 2 rear bulbs? The brake light and tail light (parking light) are the same bulb, 2 filaments, one for brakes, one for tail lights. If the the tail light filament burns out, the brake light will continue to work ok. It is quite possible that both tail lights burned out, and the brake light filaments are good and still working. Replace w/ bulb #2057. Let me know if this fixes it, if not, I'll keep working on it.
I've got a 2001 Elantra that "eats" headlights. Within the last five years, I've probably replaced both headlights 10-15 times. Last time I bought bulbs, the clerk at the Auto Zone recommended coating the connection points of the bulbs in electrical grease (which is different than regular grease). It's usually sold in small foil packages at the check-outs. Anyway, this seemed to prolong the life of the bulbs by 3-4 times. It's a cheap fix that didn't completely solved the problem, but sure cut down on the number of bulb replacements.
