Today i decided to plug my old HID kit with a new set of bulbs for the high beam But there is something weird going on and i'm not sure how to fix it.
I have a H4 setup for low/high, and also a separate high beam which uses 9005.
For the H4, i used two diodes so that my HID will turn on both in high and low . and ofcourse i'm using a relay for this. This is the diagram i used when i did my retro.
For the 9005 (high beam), since it only has + and -, i simply wired it up as normal with another relay.
The problem is: Whenever I switch off from high beam to low beam, the low beam seems to have been switched off and on, and it doesn't look good for the bulb. So i'm guessing there's some kind of voltage spike going on or something... how can I fix this?
