So I just put LED lights in my Prius and it was so easy to do and there is a lot of info on plug numbers and which ones to buy.

I just inherited a 2009 TL only 49K miles. It's a sweet car.

Now I want to add those same LED lights to my TL.

I found out the high beams are 9005/HB3 (same as my Prius) these are the plug connect numbers not the bulbs.

Can anyone tell me what the low beam plug numbers are? In my Prius they are H11.

The LEDs I bought for my Prius are called Techmax and are sold on Amazon and they are literally amazing compared to halogens

 

The TL has HIDs and does not need any modifications.

The HIDs are going to be better than the LED you attempt to replace it with.

 

Also, because I feel the need to clarify.

The low beams are HID and absolutely are not needing an upgrade, especially with that "upgrade" being $40 LEDs from Amazon.

There are multiple people that have swapped the high beam for LED, keep in mind that is also your DRL so the bulb will be running at a different power level while the headlight is off.

For the foglights, if you had a 12-14 TL I'd recommend the Morimoto XB Round LED fog which is a direct replacement for the OEM, sadly the 09-11 does not share the same housing.

 

^ Pretty much everything that he said. The Morimoto's are very good. As far as high beams/DRL's, I replaced them with LED and I'm very happy with the look and performance of the high beams now. But yes, don't mess with the HID's. At most, you can purchase new HID bulbs if you want. I've tried Philips CrystalVision and OSRAM NightBreaker but frankly, both were only a marginal improvement over stock.
