Thread: Philips DRL on 2010 RRS?

Well it's getting less relevant as LED headlights become commonplace, but they're essentially a minimal draw, set and forget, maintenance free way of significantly increasing daytime visibility without wearing out your halogens or HIDs. Typically good ones are up to 1000 lumens and 6000k which halogens can't do. The automatic headlight setting is for seeing where you're going, not being seen.

Hi Baz

I think there is evidence that DRLs reduce accidents. They are usually LED so draw a much smaller current than headlights and don't need bulb replacement. They automatically come on with the engine and switch off when headlights are switched off (although many people wire them incorrectly so that they are always on).

They are quite bright and don't just aim down so they should be visible from wider angles than headlights. This is also why they need to be off when it is dark.

Plus, they look good...

Many DRLs if wired correctly drop to 30% output when headlights are on...

The trouble is, people don't turn them off when they turn their headlights on

From the other forum, apparently they need to be set up so that they turn off when you turn your headlights off, that's the way the factory DRLs are set up AND they can't be brighter than you headlights.

Factory DRLs dim their output below that of headlights..
Some aftermarket controllers do the same.

Cheaper DRL installs are supposed to turn on with ignition and off with Headlights being turned on...

DRLs like all other lights are required to comply - most on the young demographic are just LEDs off eBay...

No the whole point is that they can be on when your headlights are off. And as Tombie says, they're wired in to dim as soon as the parkers kick in. Check out the video, they're super easy to install, and it demos their functions as well.

Last time I was out on the highway I paid attention to the newer cars with factory fitted LED DRL vs cars with just the headlights on. I much preferred the headlights as from my observations they are visible from a far greater distance. I was going to install some LED DRL but after that run I now wont bother (I might change the CCF to enable the DRL however)
