Bought an ultrastinger from eBay, the switch was seized so I bought a new one, bought a new bulb and it doesn't work. Bulb and battery work in my sl20 bit not in the ultrastinger. Any ideas of what to try next
If anything call SL or look on there website for info on sending it for warranty. Think they are still a US company. If bulb and battery work and you changed switch it sounds like it may be the tailcap. Do paperclip test.
