Premium LED equivalent bulb for 28-Volt Single-Contact Midget Flanged filament bulbs, compatible with both DC and AC electrical systems. This led incorporates a single flood SMD (surface mount diode) with the chip height consistent with the filament height on the incandescent-style bulb; this allows the light to radiate in all directions for a balanced illumination suitable as a replacement for panel post lights as well as annuciation applications. This led is not sensitive to polarity and dimmable (reduce input voltage = bulb dims; increase input voltage = brightness increases). 
Multiple light color variations to give you more application specific options. More total light output, low heat, decreased power consumption and projected life of over 30,000 hours. This is a simple, low-cost and long-term solution to more efficient and more reliable lighting compared to the inefficient failure-prone incandescent variants. 
 
Hint: General rule is to match the light color to the lens color for indicator application.
