I was trying to work out a safe but accessible space for the base of the lights with the battery compartment to go. Other than gluing it on the outside walls I couldn't think of anywhere. Then my stupid brain created more work for me when it said to embed it in the drum riser. I had to cut a hole in it on an angle so the base would line up flush. I then had to fill the gaps and paint it all again so it was not obvious it was there.
