Model a LED headlight problem

[nkaminar]

Use the volt setting on you mutimeter to measure the voltage at the LED headlight bulbs when using the turn indicators and when not using them. You will need to remove the bulbs and measure the voltage at the pins in the socket. Use the ohm setting on the multimeter to check the ground connection from the ground pin in the socket to a good ground on the engine or better yet at the battery ground terminal.
