Great upgrade to older 1156 12 volt auto light bulbs.
I bought these lights to update my existing dome light bulbs in my RV. This product turned out to be fantastic. The lights are very bright and run cool. They appear to be built well and, therefore, cost a bit more but I feel that it was well worth the investment. You can use these to replace 1156 (single filament) 12 volt automobile bulbs.
