12v bulbs

[TAKPAK]

Hi Bob. There is never a good explaination as to why bulbs blow when they do. Weak element, bad production run, etc. And as far as being made in China, well.....even bulbs marked "GE" are made in China. Those bulbs should be available at any RV supply dealer, or most automotive supply houses. Or, if you want to go high-tech, replace with the new LED bulbs.
