Flasher Relay for 2013 F25?

I would like to change my front/rear turn signals and brake lights from the OEM incandecent bulbs (7506 and 7507) to LED's. I have the Xenon HID's which was included in one of my packages. Question: Does anyone know if the OEM Flasher relay will support LED's? If not, where is the Flasher relay located and can it be switched to a new Relay that will support LED's (without giving a bulb out error)? Bottom line is that I don't want to cut wires and install Load resistors for the turn signal bulbs.

Get LEDs with resistors built in.

Thanks, I have researched it but there does not appear to be any with built in resistors for the front Turn/Parking bulbs (7507) they are only available for the rear (7506). In my research an option is to change the Flasher Relay then you do not require load resistors at all but, I have not been able to find the flasher on the F25, nor do I know if that is an option on this vehicle.

There is no flasher relay in X3(F25), the turning signal lights are switched on / off by the "computer" and the bulb status is monitored as well by the same computer. To avoid error messages when using LEDs for the rear flashers you need parallel resistors of 10 ohms (capable to handle 20W or more). A LED flasher bulb uses roughly 2 to 5 watt instead of the original incandescent lamp consuming 21W and the "bulb monitoring" activity assumes the bulb to be Ok only when consuming roughly that 21W or so. Typically in the available LED bulbs there are no such resistors in-build (10ohm/20W resistor is almost as big as the bulb itself)

Concerning the front flashers bulbs my experience (of X3 European model) is that you don't need parallel resistors if you change the original P21W bulbs to LEDs

Thank you for the information...
