they stay on until the default time (mine is 30 seconds)

That is correct.

If you want to shut them off instantly, just double press the lock button on the remote.

Thanks for the info!!!

Just completed this mod! I was lucky enough to find a used light sensor on ebay for $33 shipped, and then I just ended up buying both the headlight switch and wiring harness from ToyotaPartsZone.com for another $130 shipped. Many thanks for the great write-up, which made things go smoothly.

You rock, OP!

I've been wanting auto headlights for some time now, but then when I realized that I got both the auto function and a new turn stalk I knew this was for me. My '04 SR5 V8 has almost 100k miles on it and when I use my blinker it doesn't always register due to wear, but the new one is perfect!

Also, the HVAC and light sensor were a total pain to install. That part definitely took the longest and tried my patience the worst, but in the end it's totally worth it.

For others thinking about doing this, you may also want to replace the odometer screen at the same time since that thing ends up scratching so easily over time. I replaced mine about a year ago, but may do it again soon due to all the scratches.

Thanks for the write-up. Mod done, $6 sensor from eBay, stalk and harness for $107 from Camel Back Toyota.

What a great write-up. I am really interested in seeing if anyone has done this on a 5th gen? That is the only thing I miss from my Sequoia and as well spec'd as the '14 SR5 is I am kind of surprised it doesn't have it from the factory.

This might not be the answer you are looking for, but I have just decided to leave my lights on all the time. If you haven't tried they do turn themselves off after you turn the engine off.

I did this mod yesterday on my Sport Edition. The only real trouble I had was in removing the existing solar sensor (for the climate control). I used the suggestion from a other member and purchased the limited harness which replaces the existing harness. This gives you a factory look without the need for splicing any wires. I got the harness for around $9.00 and a used auto headlamp sensor for $75. The most expensive part is the headlamp dimmer which was about $100. It seems like a lot of money but I am very pleased with the results. I love mods where everything just plugs in. Now if only there was a write up on upgrading from the stock sound system to the JBL. A friend of mine has the JBL in her '05 Limited and it sounds pretty darn good compared to mine.

I'm sure it should be obvious, but I can be slow sometimes. Does anyone have a picture of where the light sensor plugs in? I know there's a blank you remove to plug it in, but I'm staring at my dash scratching my head . . .

Did you buy the $6 sensor used on eBay? If not, do you have the eBay seller/store you purchased it from?

I went to Crazy Rays junkyard in Hawkins Point today and was able to find the light sensor from a 2003 Lexus GS300. I grabbed the headlight switch as well but I do not think its the same connector on the bottom. Does anybody know of other Toyota or Lexus or Scion vehicles that would use the same auto headlight switch? Thanks in advance.

If somebody is interested in this modifications please let me know

I sold my 4Runner and I have al the part

Thanks

are you saying you "have all the parts"? I might be interested in most of the parts.
