Problem with lights.

[Grantstead]

Unfortunately, nothing closer to the full problem would fit in the title. I have an odd set of problems with the headlights on my Yaris. It's a 2007 hatchback, pretty basic - no CC or side airbags, but it does have power windows and locks.

First off, you know how when you switch to high beams, it still illuminates the roadway immediately in front of your vehicle? Mine only does that on the right. On the left, it switches to high-only, providing illumination far down the road but not directly in front of my Yaris. I thought it might be the bulbs, so I removed my bumper and replaced the bulbs...only to have it still do the same thing.

The previous owner of my Yaris replaced the wiring harness on the right-hand side and crimped the wires to attach them (only the headlight harness, no others). However, I took it to a mechanic and they said that the harness is getting just as much juice as it's supposed to, and both headlights are equally bright in low-beam. (though it appears that the left side's bulb is pulled about 1/2"-3/4" further back from the reflector cover thingamajig than the bulb on the right side)

Aaaand that's not all. For whatever reason, only my right DRL works...and only sometimes. It flashes when I arm/disarm the alarm like it's supposed to, but it also comes on when my parking lights are on, and when I turn on my headlights. The one on the left won't turn on under any circumstances (even though I just replaced both bulbs), and neither turn on when my car is in gear (unless my parking or headlights are on, in which case only the right-side's DRL turns on).

I have no idea why this would be the case, and haven't had any luck finding information because it's such an odd set of symptoms.
