converting Daytime lights to white LEDs
#16
Your experience is similar to mine. After many, many attempts, I finally gave up and simply installed some Philips 9005 incendescent bulbs from my Volvo 850 that just happen to be slightly less yellow than the Sylvanias that were previously in my RX330.
I tried two LED 9005 bulb pairs, both from CNLM via Amazon, that purportedly work @ 6V. The newer model's page even includes a photo of the LEDs illuminating on 6V from a power regulator. Doesn't matter. They still don't work.
Most frustrating was that my initial attempt in May immediately killed DRL functionality in my car entirely, even with the prior incandescent bulbs back in. Ultimately, I had to use the Toyota Techstream software to (1) confirm that DRL was supposed to be on, (2) turn DRL off, and then (3) turn DRL back on. Suddenly, DRL worked again. It was an excruciating level of effort just to get DRL back. Fortunately, my second attempt with allegedly DRL-friendly LED bulbs didn't kill my DRL again.
I will learn to love incandescent DRL and High Beams on my 2006. My next RX will be newer and will have a completely different DRL method.

Got the MTEC DRL+HIGH BEAM LED bubs for $89. The ones intended for the Sienna and Camry. Have them in my 2009 GS350, 2012 ES350, and 2008 RX350. Don't notice any flickering as DRLs and they are bright, but not overly so, and as High beams, they are awesome. Brighter than the OEM HID high beams in our 2015 GS350. For $8 bucks, its more expensive than most others on amazon and Ebay, but its a worthwhile upgrade.

The Techstream software seems to be everywhere. The OBD-II interface cable that I bought, , contains a link to the software right in the Q&A on the product page and also comes with two versions on a CD. The reviews for that cable contain multiple versions of the instructions to get it all working, including links to various Toyota forums where links to other versions and still more instructions can be found.
Ultimately, I got version 12.0.x to work under Windows 10 32-bit (64-bit introduced other complications). It was literally weeks of on-and-off frustration, three different eval copies of Windows 10, and one Chinese silent movie (no, seriously) before it finally connected to the car and worked. If you already have a working installation of Windows, and especially if it's 32-bit, your experience should be somewhat smoother.

I finally got BOTH of these 9005 LEDs working as both High Beams and DRL in my 2006 RX330.
1. 2.
The solution was one of two sets of "LED Intelligent Decoders" sent to me for testing by the original Amazon seller. It's this:
I hope this aids in 350rx's quest.
