    Hey guys, so i purchased my first car last tuesday and i'm excited its a prius. I got lucky and got it below Kelly blue book. Its a 2010 IV, love the navigation and sound system. Thee car had a few minor issues when i bought it (ABS/Slip/Horn repaired). My only other issue (very minor) is the driver side door sill. The light unfortunately does not turn on when i open the door. After realizing this i took apart door foot panel, plastic door guard and the door sill itself. Immediately after removing the door sill i noticed that there was a significant amount of surface rust and the led circuitry had been compromised from water and appeared to be the root cause. So i thought i could fix it by removing the led light strip and replace it with some generic 12V blue led strip lighting. My thought was that i could cut the wires from the original led and tie into the existing OEM wiring. But when i plugged it in nothing happened; i tested the led lights i bought on a 9V and it works. So then i bought a multimeter and tested the wires and i didn't get any reading. Am i doing anything wrong? Is there a particular fuse i need to check or any other lines i need to follow? Any help would be appreciated.

    Thanks so much everyone

    door sill LEDs are usually connected to the door panel lights. You can check the illuminated door sill installation thread for additional wire information.

    So i have followed the following directions for Part Number: PT922-47100

    Im trying to connect the lights to the existing OEM installation, but nothing is happening. To be clear is the OEM wiring running on 12v's or is it something different and that is why the replacement lights are not functioning?

    So you've connected the +12V of the light to constant +12v and the ground of the light to the door light's -12v trigger wire? Any other connection won't work.

    That's exactly what I have done, but no success. I don't know if a fuse is burn or where to look. To reiterate I simply tied the new lights to the existing oem wiring. Red + to Red + and the black - to the yellow -

    Door light work? is the new light 12V? Have you tested all the wires using a multimeter and verify that all the wires are working and connected correctly? There's something you've over looked.
