H7 cornering lights
Bought som H7 Cree bulbs for my cornering lights, i ordered a resistor also.
But the problem is, i can t mount the resistor on the bulb becauce the H7 socket and plug is the "same",mounted directly on the bulb(hope you undertand what i mean)
Unfornually i do not hava a picture of the car socket.
If i dont use the resistor, the bulb will flicker or just wont lighten up, and i get the broken bulb light inside the car.
Anybody knows how i can bypass this problem.

I think there are some H7 cree error-free (canbus) bulbs in the market. Most of them are made in China. This should eliminate the problem using the piggy tails (the one that you showed in the photo).

I purchased the Plasma (LED) bulbs on CardID that are listed as "cornering light" replacements but they won't work. The problem is that the cornering light function will turn on and then try to fade after a few seconds. LEDs don't fade with a voltage drop but fade with a pulse. LED's will throw an error in this configuration. AZNoptics suggest using the Phillips DiamondVision H7 Ultimate white light 5000K bulbs. They are bright white, match your Xenon bulbs and have a better scatter and light pattern than an LED bulb. I'm using them in my Bi-Xenon conversion and they look and respond great.
