I was going to ask about the hot spot in my bright lights on my 03 headlights, but when I went to go take pictures I realized it was both low and high beams.

What causes this, and how do I fix it? Clean the lenses? The housing lens is as clean as I can get it, but I haven't opened the lights and looked at the actual lenses.


It's a yellow garage door, that's why the lights look so yellow.

Brights


Low beam

 

Xecks, that center spot is a good thing. The 03 to 05 HID lights are high-intensity discharge low beams (with a fixed cut off), but only Halogen high beams. The high beams bulbs focus a broad swath of light above the low beam cut off (low beams stay on with high beams) and also send two pinpoints of light down the middle of the road. This adds some concentration of brightness at the farthest reach of the light pattern. In 2003 this was pretty much state of the art, however by 2006 BI-Zeon HIDs became the new standard with improved tech (movable cut-off) and made the early style obsolete. If you get a chance to buy a set of 06 to 08 lights from a wreck or ones that supposably fell of the back of a truck, etc go for it, it’s a big improvement.

 

Thanks Jennifer. I knew about the HID/Halogen combo on the 03-05 lights. Doesn't the cutoff look pretty bad to you though (on the low beams)? These are lights that I just installed to replace my stock lights (these are OEM lights still, just a different set).
My old lights didn't seem to have this issue.
The hot spot on the brights is pretty bad when driving. It was lighting up one very specific part of the road alot until I adjusted them (they were way too low, about 24.5" from 8' back. I put them up to 26"). Now I can see great, and very far down the road, but there is a hot spot on the trees far down the road and it really annoys me haha.

 

Yes, now I see the low beam part on your original post, my reading comprehension sucks. Maybe there are cheap aftermarket bulbs in the lights, they are known to have poor focal match, or maybe c focus instead of r focus HID bulbs are jammed in the lights. Either of these conditions will cause a very gleary low beam with poor distribution of light.

 

Nope, I swapped the same bulbs that were in my old lights into the new ones lol
