Hi, The LEDs are excellent the beam pattern and focus are exactly the same as when the halogen bulbs was fitted that's on the H7s. The H1 bulbs I had to modify the bulb holder as the LED was horizontal and the beam pattern was awful, modified the bulb holder so the LED was vertical and they are spot on, the difference is amazing, I had HIDS before but these are ten times brighter, never been flashed by an oncoming vehicle. Yes the LEDs do have some sort of driver box on them, I might try load resistors if they don't work I have a set of H7s without the driver box on, and they did bring the bulb out warning on, and yes they did flash too so may try them with the load resistors if they do not work on the other ones.
