Default ..:: The plate light situation ::..

Hi Guys!
Plate light on a 2K7 H3 Base is not working, one of the wires of the connector had been pulled out completely and there seems to be no way to put it back in, so I'm looking for that connector to replace it and then be able to hook it up back to the light fixture. Bulb and light fixture seem to be ok, is just that one wire pulled out, so no power. Any help finding the right connector will be appreciated, thanks!

  • When replacing bulbs, especially turn signals with LED bulbs, you might need to install load equalizers or an LED flasher to prevent "hyperblink" (fast flashing).
  • Diode Dynamics states that their LED turn signals are a direct replacement for the factory 3157 bulbs.
  • It's recommended to replace bulbs in pairs to ensure equal brightness and color.
  • When handling halogen bulbs, avoid touching the glass with your bare fingers.
