Bulbs, fuse, wires ,switch.
NO. the 99, 00, and 01 lhs have 3 bulbs in the headlight, a blinker, high beam and low beam. The Concorde 02,03, & 04 will interchange/work. The 2000 Concorde has only 2 bulbs (high and low beam)...
NO. the 99, 00, and 01 lhs have 3 bulbs in the headlight, a blinker, high beam and low beam. The Concorde 02,03, & 04 will interchange/work. The 2000 Concorde has only 2 bulbs (high and low beam) and has a different front facia (bumper) to meet turn signal requirements. The sad part is the mounting screws do match up and there is a difference of several hundred dollars cost between these models, but the signal lights will not work properly if interchanged with the 2000 Concorde.
Headlights that serve as a high and low beam have two different filiments in them. The low beam filiment is most likely burnt out. Time to replace it.
High beam light is out!
Yes
A possible reason that only one high-beam will work is that the malfunctioning bulb is burnt out.
Bulbs blew
possibley blown high beam light
You may need to replace your dimmer switch.
It sounds like the low beam/high beam switch is bad. Fuses are not the problem since they are built into the headlight switch and would cause headlights to blink or not come on for both high and low beam headlights.
Check fuses and high/low beam switch.
The high beam may be blown. ---- Bad relay.
