LED no way well maybe if you solder but I dont recommend it ,the wire is threaded through and wrapped into the groove and LEDs wont dim without a PWM

I saw that on my 2 crvs also these LEDs would work if they dont light just turn 180 degrees + - but may need to solder to existing fine wire,the LED leads might fit through the holes if not solder, just stick with the 12v because adding a resistor will be impossible on the holder,I have found on LEDs if you take some sand paper and sand the end of it they will not be as directional and spread the light out the sides better,I found that on back lighting on my ham radios never did it in cars because of dimming issue ,looking at the reviews people have used these on Honda and others for HVAC and dash so these look good the one with the Odyssey the grey base they just soldered directly to the board and discarded the holder I guess https://www.amazon.com/Partsam-Emit...=1564955645&s=gateway&sr=8-15#customerReviews
