Head Beams

I've read most Post about replacing headbeams with higher power beams. To me it seems the Headbeams are pointed Straight Out. Thats not good if you cant see the road. Has anyone adjusted the beams and seen any improvement.

What are "headbeams"?

Think of the stock headlights as projecting their light in a cone. On low beams the cone is pointed lower on the road and it is elevated when the high beams are activated. The design of the reflector allows some light to flood the area around the main point of the beam. I think the reflector design allows too much light into the flooded area and it diffuses to being ineffective. Think of driving in a snowstorm, the standard low beams make it seem like you are flying through space.

The newer lighting/aftermarket designs is different. Think of the light as shining like a D that is rotated to the right 90 degrees. The flat line is the horizon and when the low beams are on the light is directed downward illuminating the road better. Turn on the high beams, that leaves the low as is while illuminating farther down the road and higher off the horizon along with wider. This design along with a whiter light helps to illuminate things much better. That and it is less annoying to oncoming traffic as there is less light shining upwards. Again driving in a snowstorm, the light is focused more towards the road and it significantly reduces the flying through space sensation.

I am using the Quadratec Stealth headlights. If you look up images you will see what I mean. Other designs illuminate differently, the design on low beams to focus the light on the road instead of higher I think is similar with all though. These are just my observations and opinions.

Generally speaking headlights on Jeeps are bad. Most guys lift their Jeep but NEVER re-aim their headlights. This is typical even after they spend money on expensive LED aftermarket lights.

After aiming my TL and thinking they were good, we had our first fog... Boy was I wrong! The drivers side was pointing up to passengers 2 o'clock position and passengers side was pointing right in middle of road at 6. I got the torx long handle drivers out and re-adjusted them....HUGE DIFFERENCE!

Agreed that there's no benefit to adjusting your properly adjusted stock headlights. Only improvement is to go aftermarket or the very expensive led from Chrysler. I would suggest the 4 dollar horizontal adjustment screws as well. They really help to fine tune the beam. Good luck.

I too have found heavy fog a real benefit for adjusting headlights. The conditions are rare, but when it happens I encourage everyone to get out in the fog and check your beams adjustment. It's a real eye-opener.
