Spyder Red Peterbilt-style 12 diode LED ultra-thin marker light

This light is ridiculously thin - you might even wonder how it can possibly work! But don't worry, it's fully sealed and functional. The reflectorized background is characteristic of the Spyder series, and it's been adapted very well for the low profile.Electrical Built-in 2 prong female plug 12 volt Single function Design 12 Red diodes - 2 rows of 6 6-1/4" (L) x 2-1/8" (W) x 3/4" (H) Includes stainless steel rim Mounting 3-15/16" between mounting holes - measured center-to-center Flush mount No mounting hardware included
