DRLs ?

[Don_23805]

I've ALWAYS driven with headlights on, way before the concept of DRLs. Some previous cars had a "dropping resistor" on DRL, probably to make bulbs last longer. I always shorted it out for full brightness. MME lights revert to Auto at each turn-on. But they seem to be full brightness heads, even in daytime. Am I right?

On my Premium trim, no, in Auto mode the headlights only turn on when required because it's getting or is dark outside.

These are the signature running lights on my car.

Thanx, will check again today, now that there is real sun

It should be in low beam mode when there is less than full daylight or when wipers are activated (by rain sensor or manually by constant mode), other than that it will use the dedicated DRL lights (which are also parking lights).

There is no bulbs on the MME lights anywhere, they are all LEDs which will last the lifetime of the car (unless they are faulty for other reason). The DRLs are much more visible during daylight for other drivers than the low beam. However, LEDs will change over time when used, so reducing low beam usage will keep the LEDs at full brightness for a longer time, but might also increase condensation inside lamps causing damage to lens and reflectors (keep in mind there are almost none (or none at all) reflectors in LED lamps)

Have to see if I agree with this statement. Have to solicit opinions from friends since there are so few MMEs on the road that I've never seen one coming from opposite direction (and only 2 suspicious pasing me while waiting 7 months for mine). Beginning to think I have the only one in Richmond/Petersburg,VA area ;=)

Sorry, there might be local differences between countries. I am in europe with EU laws where low beams is required to create a significantly less light above cut-off mark than US low beams (= less glare = less visibility in daylight). The low beams are probably also running lower power in EU than in US since EU laws require headlight washers for high power low beams (= even less glare/visibility).
