I am trying to replace my daytime running lights with LED's but now that i look closer is the 9005 bulb in a is300 the daytime running light as well as the high beam? if so if anyone knows information of leds working or not let me know.

Oh did that before. If you put a 9005 LED in, your DRL will not work, high beam gone (no light out indication on dash) for it to turn on and stay constant, lock your high beam on. LEDs either go on or off. Basically your factory oem halogen bulb has two output (low and high) 35/55 watts if I am not mistaken. If you want the DRL to still work with the LED you have to put a LED DRL fixer. Most LEDs don't have two levels of output. Not like a halogen 7443 (which your break lights use). Hope this is helpful.
