Possible (y/n)? LED headlights on Prius IV 2010

The V has LED headlights, maybe a Toyota Parts Store or Collision Repair shop will have them. Of course if you go with OEM Toyota Parts the cost could be prohibitive, but on the flip side, they may be a simple plug-n-play conversion!

 

It would be interesting to see if you could just remove your IV Halogen Headlight Assembly and replace them with the V LED Headlight Assembly. If it was a simple swap, I'd be interested in doing this being as the LED would use less energy!

 

I seriously doubt the V's LEDs will just be a simple plug-n-play....pretty sure it has the auto leveling plus the washers, etc. BUT if someone can be brave enough to try I'd love to see the results!

 

From another post on this site, there was a link to JDM OEM headlights. The cost was over $3K for the units, not including shipping.

I've thought of LEDs myself and even purchased some LED H11 bulbs with as many SMD LED panels on the bulb as I could find. Light output was pretty much not existent compared to the stock halogens. As DRL, they might be useful but for headlamp units, forget about it.

 

oh LED lights... I already researched it last year and acquired few LED headlights off eBay that came from Priues involved in front end collision.

The issue was, these lights coming from collision shop all are missing the ECU as these are sold separately so shops are simply throwing away the light housing (with LED lights in it) but keeping the ECU.

Light housing can be bought on eBay for under $100 per side with broken tabs etc. Toyota sells tab repair kit.

ECU can be purchased for about $350 per side from parts.com.

I wasn't ready to spend another $700+ on this conversion, I researched a bit and learned that it's nothing more then a sophisticated DC-DC converter raising 12v current to 36v to drive 3 12v LEDs wired in serial. I am sure it's got voltage production etc and able to send the signal to the dashboard when it detects a bad LED. I think it's critical because with 3 LEDs, 1 burned out LED won't be noticeable to drive compare to single HID or Halogen bulb going out.

To me, it's a none issue so I've decided to take the headlight apart and modify the wiring, wiring 3 LEDs in parallel instead and I was able to light it up hooking up to the 12v battery directly without any ECU.

Headlight washer is needed to melt the snow in front of light because LED doesn't generate much heat in front of the light to melt off the snow but we rarely get snow in my area so this is a none issue.

Headlight leveling is required for HID and LED lamp but I rarely carry passengers or cargo so level will be pretty much constant so it's a none issue. Plus I see everyone installing HID kit and not care about the auto leveling.

I still have to do the wiring modification on other headlight and take off the bumper to mount them but haven't had a time.

My point is, this modification can be done relatively cheaply but it's not a simply plug and play. but if you are brave enough, I've done most of research already so just follow my path.

 

TJP74 - Do you have pics of the interworkings of the LED headlight? Was it pretty easy to convert from serial to parallel? It sounds like a pretty simple task, much simpler than the retrofit route I was going to go down and they'll be OEM quality.

 

thank god toyota delivers led+solarroof together in europe ;P

 

I see that CARID carries a stip of LEDs that will mimic Audi. I have been waiting for something like that. I wonder how it would look?

 

I think Fog Lights and the LED Headlights should be an accessory, they could make alot of $$$$.

Actually Toyota should make the both of these standard since it could be viewed as a Safety Feature

 

Don't forget the rear height control sensor...
