The Diode Dynamics SMD12 LED board pair in red upgrades two 74/194/BA9S or festoon-size incandescent bulbs for added color and improved brightness. Each board carries twelve SMD chips in a 4x3 matrix delivering roughly 118 lumens apiece. Installation is a simple bulb swap using included adapters; boards may be mounted inside housings with 3M adhesive. Constant-current circuitry and transient suppression improve reliability and come with a three-year replacement warranty.
