Just ordered some LEDs with built-in resistors for the rear turn signals, but it appears that the turn signals require two bulbs on each side on the 2007 model?

Parts listing shows 2 per side

Get an LED compatible flasher instead, verify but I think the CF18 will work in your car. I will warn you, every one of these I've tried the 1st flash is longer than the rest I find this very annoying. Other people don't mind it.

.....are some of these tail lamps integrated LEDs meaning can't replace anything?

I thought about the flasher, and I've done LED relay flashers on other cars before, but it looks like it's a giant pain in the *** to replace on the LS 460. I want to see if he's built in resistor LEDs work. So I need to buy two pairs of LEDs just to do the rear turn signals?

Yes 4 bulbs total. Which bulbs are you looking to get? Stock bulb is about 4 watts each so a 25-30 ohm resistor per side would be about right. The flasher might use the front bulbs as the load sense so it won't matter what you put in the rear, test this by removing 1 or both bulbs see if you get hyperflash.

They are CANBUS error free with built in resistor that supposedly works with Lexus. I originally ordered one set for the front and one set for the rear but I guess I need to order another set for the rear? So strange that there's four turn signal lights in the rear
