Ok here is the deal. I have Lumanics Titanium bulbs in my car right now at the moment. Tonight while driving home I had a car coming at me with his brights on so I flashed him to let him know...shortly after that (like 20 seconds) my headlights went out.

Now, the blue brights dash light is on no mater if I have the lights on normal or on the brights...the fog lights stay on, dont turn off if I move the lights to the brights.

So I got home and put the stock bulbs back in a same thing, all I get is fog lights and the blue bright sysmbol stays on....what could of caused this, and what should be done to fix it. The car is only 2 months old, Dealer ship takle this one?

Sounded to me like he has the high beam indicator, fog lights, and no headlights right now...

First, check fuses.

These might help - might not. If you've made no mods to your foglights/headlights (and if the foglights were dealer installed) This might very well be something for the dealer to handle after you check the fuses.

Anyways.....

I went back out both fuses for the headlights were fried. so I swaped them out from 10s to 15s to see if that will help.

The wires can handle 5 more amps, if it's a short the fuse will still pop instantly. If you still have this problem, run relays and thicker wire and use your standard wire for the trigger. That's what I'm doing to run the high and lows together when the highs are on. Old school chevy truck trick

you will be fine with those fuses for the time being, just go and get a set of fuses soon and replace them with the correct ones.

If it's a short, the post above is right, the fuses will pop quite quickly, but if is the basic overload that I suspect, the larger fuses will allow the wires to heat up a lot more than they should. Those wires are buried in a wire loom with a bunch of other wires and have a difficult time unloading their heat.

There is a reasonable chance that the insulation on the headlight wiring will get too hot and be damaged, and in turn possibly damage other wires nearby. Enough of that, and you can get a cross betweeen circuits, more heaating, unexpected circuit activations, and even an electrical fire.

That is why those fuses are there, and why they are the size they are: to protect the wiring harness.

If 10 amp fuses (one for each headlight) won't hold, you are pulling more power than the wires are designed to handle on a long-term basis, and need to find out WHY.

The normal headlight filaments only suck about 5A each...
