Replace incandescent rear license plate lights with LEDs

Anyone tried this?

Seems like it might be a good idea. The LEDs are brighter, last longer, and use less power. Not sure why Tesla wouldn't have used LEDs to begin with. Seems like a rather non-invasive upgrade. Anyone see any downside?

Ordered mine 2 days ago. Will post when installed.

I did mine. No downside. You can see the difference here with the LED on the left and the original bulb on the right.

There's an extensive thread on it over at TMC, it seems to be quite a popular project.

Just ordered a set of bulbs myself. I'll give it a shot.

Why use halogen lamps in this car in the first place ?? Just a matter of cost?

The Prius comes with optional LED head lamps. Would be better for the range vs. halogen and xenon

Not sure why LEDs were not used on the license plate - the Model S prototype in 2009 had 6 LEDs. I suspect it might be more about the molded lens. Perhap they got an assembly from the Benz or Toyota parts that fit, and the LEDs would have required something custom (with more time and effort). It's really not that big a deal - but I do think the LEDs look better.

They could have used the current assembly and use the same LED we are buying, but perhaps there is a concern they could rotate under vibration and not shine downward? I haven't seen any problems in a week of use.

As for the LED in the headlights, I suspect it is a matter of cost and maybe additional engineering effort that they needed focused on more critical areas. LED headlights are clearly much more expensive that halogen or xenon.

They look great.

Just for ha ha s.......

18 hours of night driving, saving 18 watts of battery per hour will give you 1 extra mile.


I definitely want to do this at some point.

Now, if anyone figures out how to replace the side blinkers with LED's that would be nice.

FYI, I completed this mod this morning. It was very easy, and looks great! Every little amp saved helps!

Got my LED's yesterday!!!! Now if only I had my Model S. :(

Can someone recommend an online store to purchase the LED? How hard is it to install. I am getting my car on Monday!

I've used VLEDS for years. They are a bit more, but I've tried other sites that are a few bucks cheaper, but they have failed over time. The VLED units are still going. Here is a link for the part.

You can choose between 5K (pure white), or 6K (blue tint). I used the 5K. If you follow the link in the original post, that article has a link to the eBay store where you can buy them. That is where I bought mine. $5.99 for two, free shipping. They were a piece of cake to install. Only took about 10 minutes. All you need is a Philips screwdriver.

mkh1437 and super67cobra - Thanks for the assist

Can someone tell us (those awaiting delivery) what LED size is correct to order? Light model # ?

While I await delivery ( hopefully this week although I'm sure this NE blizzard will slow down the pace a day or two) I'd like to order them to help pass the time.

@SteveP5664 Follow the link at the top of the thread. It has a link to the exact item to buy on eBay.

I installed mine this morning too. I had to install mine twice, because I installed both of them backwards the first time. Make sure you test them by turning on the the lights first before you put the screws back in. There's no polarity indication on the LEDs, so you need to guess and hope you put them in the right direction. If they don't light up, just flip them around the other way.

Has anyone tested their AM radio reception with these. Changing passive resistive components to active components may cause RF interference to nearby radios. 1 watt is a lot of juice and may saturate the freq spectrum of your AM tuner if it happen to leak in the RF band. I just ordered some but don!t really listen to AM radio anyway.

Thanks @Schlermie - I forgot to check mine! One was working, one wasn't. Quick turn and I was good to go.

I checked a moderately strong AM station and flipped the lights off & on, but there was no audible change in the reception. Even though the LEDs are active devices technically, it's just DC current flowing through them, so I wouldn't expect any interference.

Exactly. The "frequency" of DC is zero, hence no RF.

I did this mod. Piece of cake and it looks great!

No problem to install. Looks great and is easy. Saves some energy as well.

just to be sure, i ordered the led lights with 2 leds per light. it seemed to be what was indicated. is the correct?

These are the ones I used. Bought from eBay for $5.99 including shipping (click on image for eBay link):

I got the AGT LEDs from ebay as well and they work perfectly. Took all of 5 minutes and a Philips-head screwdriver to swap them out.

Can anyone tell me why mine keep burning out? First they begin to flicker, then fail entirely. It takes about 2 weeks. I've tried so many different brands too...

@seegem no idea. That has not been my experience. I replaced mine in February, and have had no problems so far.

Very strange. Had mine for about 7-8 months without a problem.
