LX470 No Crank, No Start after LED Headlight Swap

[JustEthan]

I am looking for some help after attempting to swap out might headlights. I decided to move from plastic headlights to aftermarket glass housings in my 2007 LX. As part of that change, I decided to try installing some Hikari H1 LEDs as well.

I pulled out the old housings, swapped one, confirmed the LEDs light up as expected, and finished the setup. After wrapping things up, I am now experiencing a no crank/no start and a flickering dash when I turn the key to ON. Aux appears to work fine. The headlights turn on as expected in AUX. The battery appears to be connected properly and is secure.

Video attached.

Are they CANbus compatible?

Have you tried starting it with the LED's unplugged?

Double check battery post clamps and how many volts at battery.

OK, thank you all. The car did start with a jumper. Battery posts appear to be fine. I don't have a multimeter at the moment, I'll need to collect one.

I have not seen the car behave in this manner during prior battery drains/issues. I will check the voltage and charge the battery to see if it needs to be swapped, it is now 4 years old.

I lost my mind because the car JUST had the starter swapped after it threw a low voltage code for one of the knock sensors. New headlight housings look great and I will check the cutoff on the Hikari LEDs once it is dark. New fog lights incoming shortly.

Please forgive the insane amount of tree pollen. The LX is in fact Onyx Black, but likes to pretend to be Nori Green.
