I converted all my exterior bulbs to LED's a year ago and all works fine. I hope you did buy Amber colored bulbs and red bulbs to replace in the appropriate places, only difference if you replace with white is the colors look a little funny. Pink instead of red for the rear clearance and the rear side marker light. The white bulbs under the amber lenses don't look too bad. One other thing is the LED's in the side marker lamps that come on with your turn signals aren't bright enough in the daylight so I left the original bulbs in place there.
