Can someone please suggest an LED blinker relay that's preferably available to buy on ebay.co.uk
Also a general location of the relay would help me out.

I know I can use resistors but that kinda defeats half the purpose of LED bulbs.

 

If you hadn't found out yet, there is no blinker relay. Hence no way to install a LED blinker relay. The blinks are controlled by the BPM I believe, and when the bulb fail system shows incorrect resistance, the blinks happen at twice the rate. That way you know your blinker is out. Lol.

So you might have to use resistors. I have been considering LEDs for certain areas, in particular the dome and trunk lights. I tried some, but they were way too dim, and the color was really off. A lot of LEDs are too large for the interior light fixtures. I did use a pair in the headlight twilight bulbs, and they look great! But.... I got the bulb fail warning.
