This LED is designed to fit nicely into start and launch ball button assemblies.  It is slightly thinner than our other Ablaze LED bulbs.  The bulbs will work perfectly on 5v circuits as well at 6.3v circuits.
These LEDs are AC/DC, meaning they can be used in both controlled (inserts) and uncontrolled (GI lighting) sockets. 
Available only in Cool White, Warm White, Red, and Blue.  Choose a color from the drop-down menu above.
Warm White works great for yellow or green buttons.
