Check the fuse for the high beam headlight circuit or possibly a faulty selector (on the steering column) switch.
your bulbs are burnt out. when you switch on the high beams its only the high beams. but when you flash your brights it lights up both high and low beams.
Check to see if the foglight switch is on. Brights (high-beams) are automatically disengaged when fog lights are being used.
the lights that arnt your brights, the main ones that come on when you turn your lights on, usually dual stage but sometimes are not
Generally speaking, high beams and low beams are two different elements in the headlight bulb, so if one is burned out the other can still work fine. you will need to replace the bulb.
Your high beams work but your low beams do not because the switch is broken that switches between high and low beams. Electrical switches wear out.
Bad dimmer switch.
That car uses a single type 9004 bulb on each side of the car. The 9004 contains two filaments, one for low beam and one for high beam. If the high beams work but the low beams do not, then either the low beam filaments in both bulbs have burned out or there is a fault in the low beam feed circuit.
low beams my have burned out
As a guess both low beams are burnt out The daytime running and high beams are the same light filament. Or the fuse or the relay for the low beams.
Bad bulbs?Bad Hi-low switch?
If low beams do not work and the high beams of a Mitsubishi Eclipse do, it is probably due to a corroded connector. Simply clean the connector and add some petroleum jelly to the terminals.
Why all of a sudden the low beams dont work but everything else does.
