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.
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.
Bad dimmer switch.
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?
It is not safe, When you thow away a computer, it sends harmful radioactive beams
they by attracting the suns beams of light and using these beams of light for energy
check all the wires that ground coming from the headlight
Check the dimmer switch and the electrical connections.
Take your car in to have it checked. Turn signals should work without high beams.
Check your owners manual.
