The front you need to remove the whole front panel. I think there are 6 - 8 screws
on the driver side that have to come out as well as the windshield and plate under
it. I think the side lights up front are T10 base.
The rear has me stumped too. I took out the 4 screws and couldn't go any further.
I wanted to upgrade the brake light before installing the Givi rack. I usually change
the 1157 taillight bulbs to 2357 as the 1157's are 21 cp and the 2357's are 32.
The side turn bulbs are special, an 1156 fits but the locating numbs on the side are
different. The reason is they don't want you putting a clear bulb in there. I heard you
can mod a 1156 by cutting off one nub then it will fit (but make sure to color it yellow!).
Note: Took all the panels off and removed the rear bezel, it looks like it should slide out after
the 4 screws are removed (but wouldn't easily for me). The brake light is similar to 1157 so the
2357 will work. I changed the licence plate lamp for LED (just cause I had one) it takes a T10
base.
