so ive changed most of my 04 ESS330 front bulbs, new OEM HIDs, white foglights and while LED front parking light to replace the dated yellow look of the original incandescent 194s, but now the amber burned out caution light on my dashboard lights up, are my new parking light LEDs whats tripping it? everything else is halogen or HID

Bulb out circuit is load based you either have to add resistors (which negates all the nice power savings) or simply remove the bulb from the cluster that's what I do. Fair warning: don't power up the car with the cluster removed you'll trigger an airbag code or 3 which requires a scan tool to clear.

Did your car have halogen headlights originally?

so the front parking light are infact monitored by the Canbus? what confused me is that i thought only the headlights Low/High beams and indicators are monitored

I'm not sure how it works on your car. Isn't there a warning for the auto headlight leveling and one for the parking light bulbs? Post a picture of your cluster if possible.

unfortunately im too far from my car right now to post a picture of the dash, but im sure i dont have any other fault light other than the "burned bulb light"

Too much to ask for Lexus to call it check engine light huh.
