IBJ - thanks & will do
DC - you'd be cutting off four (or three) OEM indicator lamps and attaching the LED lamps... need soldering gun, wire cutters, a little shrink wrap, two diodes... you'd need to solder the two small diodes to the turn signal indicator lamp (otherwise the lamp it won't blink)...
Disassembly of the OEM bracket and assembly of the LED bracket... not difficult. The bezels on the LED's are machined so they drop flush into the counter bored holes in the bracket then secured with a nut from the back... the indicator housing & backer attaches & assembles with 4 screws.
