How to Make High Beam and Low Beam Lights Turn On Simultaneously?

[Katelyn]

Bend the diode pins into the appropriate shape, insert the positive pole into the high beam relay and the negative pole into the low beam relay, utilizing the principle of unidirectional conduction to achieve this. Connect the filaments of the high and low beams together before the switch, rendering the original switches for both lights ineffective, and only use the adjusted switch to control them simultaneously. After reinserting the high and low beam relays, turn on the low beam, and the low beam lights up; when the high beam is turned on, the high beam lights up while the low beam remains on. For single-unit lamp types, the low beam is on the outside and the high beam is on the inside. In low beam mode, only the low beam group is activated; in high beam mode, both the low and high beams turn on simultaneously.
