i got me some new lights for my 08 Fit.
i'd like to wire my headlights so that once i go to hi beam, both the low beam and hi beam lights up. Currently only one is allowed to light at one time.
Can anyone advise me how to do this please?

 

Speaking for the GE model. The highs and low, use the same bulb. So only one setting can be on at a time.

 

If you change your headlights to aftermarket projector headlights, you can wire both high and low beam to be on when you turn the high beam on.

 

but the question is how do i do it?
do i need to use a relay or something?

 

anyone .....can you help me please?

 

If I were you, this was I would do to accomplish the goal.
Buy or custom wire with relay. Both low beams will get power directly from the battery. However, use OEM low or high beam to trigger the relay. So it won't void your car warranty since you do not modify any OEM harness. Additional, you can return to stock without a trace.

Please let me know if you need more clarification or diagram.
