Halo rings

[flybobbie]

Having taken apart and modded the headlamps, i noticed the led halos i fitted not as bright as tested.
I have access to the wiring so measured halo voltage, as i knew they dimmed.
Measured voltage to halo headlamps on dip, voltage just over 3 volts, no wonder the standard halogen bulbs are dim orange colour.
In drl mode it's 9 volts.
So still not the 12volts i used on the bench testing my after market halos. (i thought they went from 12 to 9 on headlamp on).

Led replacement bulbs must have a wide operating voltage of 3 volts upwards, perhaps internal regulator starts at this volts up.

The FRM (footwell module) controls the lights..depending on how it’s coded it has a major yes major effect on DRL lighting…

I wonder if my Foxwell reader can adjust the volts.
I either leave as is or make some circuit to drive them at 12 volts all the time.
Have opto isolated relays with wide operating voltage i could use, but wonder if the bulb monitor would see them as bulbs.

When you use a product that can code the lights the code levels are dim, bright , extra bright etc…so that correlates IMHO with changes to the voltage to the DRLs

Carly can adjust the DRL brightness

Well read some write up on my Foxwell, says it can adjust lights.
Will have to try.
Thanks for making me aware that's possible.

I did notice videoing the lights they are pulsing rapidly, i wonder why, unless constant monitoring.

You know you can adjust the DRL brightness via the dashboard menu?

 

[flybobbie]

You can select drl on or off on the iDrive. When on they run at 9 volts in the switch "O" posn.
Then they go 3 volts dim with headlights on.

Dont worry about that chum, all that matters is what the human eye sees, cameras have all sorts of things like interlacing, frame rates etc which can alter actual appearance. Thr 'flying rods' conspiracy is a classic example.

Don't think Foxwell will code the lights.
Got some old Fotek opto relays, they can be switched from 3 to 30v dc. So just need a 12v supply for leds.
It's just as the leds shut down they flicker, not a problem. Think opto relay will dampen that out.

 

[flybobbie]

So used the Fotek ssr25DD solid state relay.
I tried feeding headlamp "on" voltage after a diode to power the halos at 12 plus volts. Trying to keep the side light function.
It didn't like that, the headlights didn't light up, perhaps some circuit protection.
So headlamp "on" fed to the Fotek, then after diode. All works great. Halos and spot see 12-14 volts and bright.

To be honest the Fotek might be acting like a diode.

If you knew what i know about interlacing, a lot of folks would have had their speeding finds revoked.

If you have the skills in that area I believe you, can you share if its appropriate??

All out of date now going back to early days of trying to read number plates with low res. Sony cameras.
