Hi! Just want to know if anyone has changed their drl to led? I have a 2006 xle and I tried replacing it with led but the problem that i came across is that if I replace one side, the led works but the other side doesnt light up. When I replace both bulb to led, it doesnt light up at all. I got load resistors and still does the same thing. Does anyone know know how to fix this or is it not possible to do on the sienna?

So you want to run without high beams?

Not possible on sienna...........

pleaseexplain what exactly u are trying to do? Strip LED, or LED buls in the drl socket or tapping inot the power feed of the DRL and running an :LED strip etc etc etc

"DRL Sockets" = High Beam 9005 bulbs. Unless he intends to isolate the DRL function from the high beams, it's not going to happen. However, he could simply pull the jumper to disable the stock DRL/high beam function, and build his own LED light circuit that either has the LEDs running all the time that the ignition is on, or get fancy and have them on with the ignition but interrupted and turned off when the headlights are turned on.

I just wanted to change the bulb to led. I did the same thing on my 2010 wrx, same, drl/high beam and it works fine. Nothing fancy just wanted to plug and play if possible.

You found an LED cluster that puts out 1700 lumens? Even if it was that bright, the beam pattern in that reflector assembly would surely suck.

They way the DRL circuit works is, it cuts the applied voltage to half, so if the bulb is 12v the DRL circuit is supplying only ~7vlts to the bulb and hence the dimmer output....how I know this.....the below is my failed attempt........in all my previous vehicles I would increase the light output by switiching the bulbs from the standard 55w/65w to a much higher rating like a 100w/120w and ofcourse to do this you have to change the harness as well. You can get heavyduty harness adapters to do this mod. I tried doing the same as I wanted the highbeams and DRL to be brighter and not loose my DRl functionality.........but when I did this the DRL would not work neither would the straight high beam work cause the circuit is set to supply only a certain value of high beam voltage and drl voltage.....it may be voltage or amps or watts......but in any case it is set for a set value for high beam and a set value which is half of high beam for the DRL........so basically you cannot fudge around with the highbeam and DRL.....what i did in a effort to increse the visibility using the DRL was switched the bubls with the same rating to a 2500lumen bulb (YELLOW bulb)....now the DRLs are much brighter ....

hope the above helps....BTW IMHO DRL is one of the best safety feature on this van that comes standard, if you notice all the newer vehicles this feature has become a standard feature.....

wow Javvy that explains a lot. Thank you!!!

Sorry for bringing back an old thread, but to answer your question diamondsienna, yes it is possible. However you end losing the functionality of your high beams as the bulb is not bright enough. It will function with the DRL and will also turn on with the high beam.

These should work too.

Given the advances in emitter technology, this will eventually become practical. Right now you are trading your safety on a dark road for good looks in the daytime.

We know that in HIGH BEAM mode, the bulb socket receives the full 13.5 volts, while in DRL mode it gets around 6-7 volts. A 9005 incandescent bulb will be full 1700 lumen at 13.5v, about 350 lumens at 6 volts (half the voltage = 1/4 the power). The "decoder" is likely a buck-boost to level out the voltage at something between these two values, and the LED's are wired to correspond to it. The Cree units says 5 watts for the front emitter, and with their mid to higher end products I'd figure that we are looking at around 600-800 lumens or so? The 5050 emitters stacked around the side are garbage - around 20 lumens each, so another 250 lumens but with poor spread given where they are located. Net is that it's a pretty DRL, but would likely suck as a headlamp.
