hi hi
i got some H7 HID's for my parents car recently , told it was 100% bolt on.
Seemed ok to take off the covers and remove the oem bulbs , and use the included power+ground wires to simply click into place. One side works yah.
But doing the exact same thing on the other side , bulb dosent work. I swapped bulbs and wiring , and it turns out the ballast may have an issue.
But on my final test ( 1st working ballast onto 1st side) it no longer works.
This is training my brain....
What could stop ballasts working ?
Can swapping the power/ground wires accidentally cause any issue ?
OR is it , that after trying this with the car off the battery is drained so wont produce the oomph to light them up ?
Any thoughts thanks
