Question Rarely get flashed to change from Hi-Beams -why?

Greetings,

I have three lightning questions;

Ok this is likely a dumb question but I've noticed that I almost never get flashed with dual Bi-Xenon (Lo and Hi) lights on. Is there some kind of auto dimming feature or motor driven feature to move lights slightly away from oncoming traffic by means of an opto sensor of sorts ?

I've seen where it's possible to code into the DME and ask that the halo lights are driven to near 100% or full bright - I think those are incandescent type and would that produce much higher heat ?

Do the aftermarket LED halo replacements last long ? I've heard of mixed reviews about them lasting for a few years vs. OEM (standard incandescent) lasting 6++ years, is this true ?

Thank you,
Merlin

Auto high-beams were an option on the car. Check your build sheet and see if you have them.

I would not run the halos brighter; as you said, you risk damaging the housings or wiring. Have you ever priced out replacements? Pretty expensive. It would also look pretty obnoxious.

The LED aftermarket halos seem to be hit or miss. I see a lot of people complaining on here about how they flicker or go out. Even though they're warrantied, that's a real hassle to keep replacing them all the time. For what it's worth, my OEM halos were 6 years old when I sold the car and still on the original bulbs. They're not running with much power so they'll last for a long time.

If you don't have automatic dimmers, the reason might be that many pople aren't sure whether they are looking into high beams or low beams, since the HID lowbeams are substantially brighter than standard halogens, and both low beam and high beam lights are in the same housing. Unlike most cars with 4 headlights, the inner pair are not the high beams. Indeed, the second set of headlights (the inner pair) only illuminate when the steering wheel is turned or the turn signals are on (since the main beams are directional, and shift with the steering).

I'm, sure they don't like it but probably don't know if you just have really bright low beams or misaligned headlights.

The "high" beam is just the low beam hid with the shades moved up so it goes higher. The high and low are the same projector.

Maybe nobody is flashing you because everything is working correctly?

If you don't know if you have auto dimming, why aren't you dimming as cars approach?

Run your VIN # and see if you have S5ACA.

I'm surprised you aren't getting flashed with your high beams on. I do usually end up adjusting my headlights UP a few notches from the factory setting so I can see what's ahead of me at highway speeds. Maybe your headlights are adjusted LOW. The only way you'll know what others are seeing is to have someone else drive your car at you with the HIGH BEAMS on!
