Honestly? At the junkyard, or on eBay.
Check bulb if other side front is working.
I don't know, I have the same question.
As previously said. Dead, or weak battery. The light you're talking about is a blinker signal light, not a check engine light. It's just coincidental.
Probably just a burned out bulb in the front one. Those bulbs have 2 elements so the marker light will still work but the blinker wont.
It comes out the back of the light housing.
when you flip your blinker on, a relay in the circuit is activated which turns the light on and off. also, the front blinker and rear blinker usually alternate in turning off and on, so when the back is on, the front will be off, and reverse.. that's why when a bulb is out, the clicking sound in the vehicle goes faster than when both are in working order.
You remove the headlight to gain access to the back of the blinker housing, you can reach into the back of it and pull out the light and cable it's attached to. It's a pain.
There is no such thing as blinker fluid, a blinker is a turn signal light. They do not require any fluid. Brake fluid goes in at the firewall in front of the driver there usually is a plastic top with a round metal thing behind it.
The 2000 Hyundai Excel indicator light and brake light might stop working all of a sudden because of a burned out bulb. Check all bulbs on the brake lights and turn signals. This problem could also be caused by a blown fuse or a blown flasher fuse.
An L.E.D blinker is an L.E.D light that blinks on and off.
Sounds like the signal switch is at fault.
You need to remove the head light, which is rather simple, and reach through the opening from the head light to replace the light bulb for the blinker.
