I installed some hella high wattage headlights about a year ago, the lights are superior to the stock bulbs which have poor illumination. The problem is last night out he blue I have no headlights just fog lights. Anything I should check? Anyone else have this similar problem? Thanks in advance.

My first suggestion is to keep it simple. Check the bulbs to see if they have failed. If so, then replace them. If not, then you may have a bigger problem on your hands.

You replaced the OEM bulbs with higher wattage units? How much higher?

Each headlight has a separate fuse but both are controlled by a single relay "upstream" of the fuses. Since both lamps have failed at the same time I suspect the relay may have failed.

I think 70 watt/110 watt quite high I know but the stock lights are very very poor and dangerous IMO.

Might be more dangerous to run that kind of wattage through the OEM wires.

I found that I greatly improved the OEM bulbs with better aiming. I agree, that initially the headlamps were terrible but I tweaked the aim and now they are pretty good.

holycack-

Let's do a bit of trouble-shooting. I assume you have eliminated the bulbs as the problem.

1) Do the high-beams work? They utilize a different set of fuses and different relay from the low-beams.

2) Are the fuses intact?

Halo
I vote blown fuse or melted wiring on this one (in that order).

Chances are..you melted the wire harness caused by the heat generated by the higher wattage. They make heavy duty harnesses, but I would stick with OEM wattage.
