LED marker lights

Tried to replace #67 bulbs with led bulbs, listed as 1156. They are single post bases, so can't turn around. Used a small 12v battery to check out and they worked. Any ideas...

  • Reversed polarity. When an LED light does NOT work when installing, the 12 volt positive must be on the correct positive input to the Light assbly. Doug
  • For only a few bucks each you can replace all of your marker lights with exact size replacements that are SEALED, brighter LEDS, and have two leads to connect to your existing wiring. This type is sealed so there are never any bulbs to change in the future.LED lights
  • Call M4Products.com, I just replaced all my inside lts,and all clearance lts.works great
  • Check the polarity first.
    The center pin should be 12 volts DC positive. The shell should be the negative.
  • buy the more expensive replacement bulb that are polarity free (non polarized) or pull the lamp assembly out, switch the wires, glue it back on.
