I may have a solution for you, but the # MCL32RBB is a fairly low profile light at 1" so the only alternative would be a recessed mount light. I recommend checking out the Optronics LED Clearance or Side Marker Trailer Light - Chrome Plated - 2 Diodes - Red Lens # MCL71RB, which is also a 4" x 2" x 1/2" thick LED light that might fit the bill.
At this time, this would be the only solution we have that is similarly sized and is less than 1" tall/deep. view full answer...
