Wow, you stuck in super white bulbs in your indicators? I thought cops REALLY didn't like that...which ones did you exactly get? Can you read the name off the box?
The indicators are merely attached to the car via a tab...all you have to do is first remove the bulb from the indicator, depress the tab, and the indicator comes out. Then you merely put in the new indicators, and the tab will snap into place, and replace the bulb. There is no fancy wiring job required.
