Not true. The DRL takes the low voltage current and upconverts it to a higher voltage. When you flick the headlights on at night, there's no current going to the high beams. Flick the high beams on, it's full voltage current being sent, passes straight through the high beams, they still come on.
I didn't know that.I guess my service advisor didn't know that either.Not many would ask to turn off DRLs.
Thanks Steve.

Friendly tip, don't ask Lexus SA's about aftermarket parts/mods
As far as the LED DRL,don't you lose the high beams?
The LEDs can't produce lumen light output light like a halogen bulb.

When I had my IS350,some on that forum said their dealers wouldn't turn off the DRLs.

If you have replaced the high beam bulb with an LED, the LED lamp does not put out the same output as the original halogen lamp. The light will light up, but you won't have effective high beams like you do now. They won't put any light output down the road...when you hit the highs you'll essentially have...DRLs.

yes and no....they do have a considerably less output than a high power halogen...on an empty road with just your lights, the multiple LEDs in the reflector housing will throw some light. Whether that gets washed out by your low beams below the cutoff, or other oncoming cars, i dunno. But if there's oncoming cars you shouldn't have your beams on anyway
I really don't care but do like the look.
High beams I want as I visit my daughter and friends who live in a country setting with no street lights and plenty of deer..

Not cool IMHO, we all have to share the public roadways with each other, and you may think that you never use your high beams, well you don't use them until you need them...and with this upgrade when you need them they won't be there. As that person who might be walking along that dark road one night with you driving along with no high beams...I'd appreciate it if you kept your car at least street legal.

The downside of this is that it's going to be like driving around with HID High beams on during the day. And if you lived/drove in the oncoming direction while on the road with me, I'd probably hate you. That and I'm pretty sure it's illegal.
Don't be one of those d-bags with blinding HIDs on all the time. If you install HIDs, aim them properly, and use when necessary.

If you install a PnP HID kit in your high beams, you will need the same type of relay as I posted for the LED bulbs. Reason being, the HID kit will not run on the lower voltage signal sent to run the DRLs.
