I've been searching the forum for a while, looking for a viable solution to upgrade the 2018 LEAF S and its horrible low-beams.
What do you all recommend?
I've read that the LEDs from the SV and SL models won't work. Fair enough.
There's talk of a simple halogen replacement bulb from OEM to improve the low-beams. The high-beams work fine. Any idea which bulb I should get and in which size?
Is there a replacement for the entire headlight assembly to an LED which won't blind people, and is legal in California?
These lights are so bad, I can barely tell they're on at night, and I'm not getting adequate visibility for the speed of free-flowing traffic in the HOV lane at night. This is one mod that needs to be done ASAP.
Any help is appreciated!
Ok, here is my opinion. I suspect the incandescent headlights in LEAF suffer not because of the quality of the bulbs or reflector, but rather the voltage that is delivered to them. LEAF's nominal "12V" supply tends to be a bit lower than your average ICE vehicle. Boosting that directly might be possible, but there is another way to increase the voltage supplied TO THE BULB.
By rewiring the headlamp circuit using heavier gauge wiring and relays, you can eliminate some of the voltage drop inherent in the circuit and increase the BULB voltage. Incandescent bulb light output is highly sensitive
to voltage. A small increase in voltage can yield significant improvement in light output. If I ever get around to it, this is what I would try first to improve my high-beams performance (I have LED low-beams): http://www.danielsternlighting.com/tech ... elays.html
Here is a chart showing the relationship of light output and bulb life to voltage for incandescent bulbs:
