These 12V LED bulbs are manufactured using two different types of surface mount diodes (SMDs) and compact circuit boards.  They feature 4 side firing 335 Series SMD chips and 1 forward firing 5050 Series SMD chip.  Each of our 5050 series SMD chips contains 3 LEDs for a total of 7 LEDs per bulb!  The combination of forward and side firing SMDs provides incredibly bright light at over a 270 degrees viewing angle.  A single SMD chip provides nearly 4 times the light of a traditional LED.  They are the brightest LED bulbs available in this small of a package.  Simply put, there is not a brighter bulb available in this size!  These bulbs are manufactured to our specs using custom compact circuit boards allowing the bulb to be smaller than similar bulbs on the market.  This makes our able to bulb fit into a lot of places that others will not, including gauge clusters!  Visit our tech section for more information on the differences between LED and SMD technology.

These bulbs feature a BA9S bayonet type base (see chart for base compatibility).  They provide superior results in applications where light is needed both from the sides of the bulb and from the end of the bulb to illuminate the intended area.  These LED bulbs are the best choice for for gauge clusters, automotive side marker lamps, and more.  Choose from six colors or mix and match to suit your needs.

Benefits of LED bulbs include: Low current requirements, low heat output, extra long bulb life (avg. of over 10,000 hours), no bulb fade with age, increased brightness, vibration resistant, and many more.

Note: These LED (SMD) bulbs are specially made to be non-polarized. They will light even when presented with reversed current.  They have a built in bridge rectifier that automatically detects the current and ensures that diodes receive the current flow in the correct direction.
