Re: [EVDL] Nissan Leaf 2013 dim headlights at 14V

[Jay Summet via EV]

I haven't noticed that the headlights on my 2015 Leaf were too dim (I 
wouldn't call them super bright, but when you switch to high beams they 
certainly seem to be perfectly adequate), so perhaps they fixed this 
issue in later model years?

The (2013) Leaf uses halogen bulbs, but runs the 12V system at too low of a
voltage to get good brightness from them. We had the ssme issue with our
2016, and changed to LED bulbs to resolve it (the LEDs will run at full
brightness at anything over 9V).

Hope this helps,

Roger.

Sigh.  See below.

For anyone interested, I've just started investigating it, but it looks as 
if Claws Mail does a good job of handling incoming html mail, while flatly 
refusing to ever send html mail under any circumstances.  



>From Cor:

Alternative is to increase the wire diameter of the run to the headlights.

Many manufacturers account for voltage drop between battery and load 
(headlight) due to the (cheap) thin gauge and ~5 Amps per headlight.

So, you may find only around 11V on the light assembly and the bulb is 
designed for this.

And that means you can increase brightness of your headlights simply by 
splicing a thicker wire into the longest run of wire.

Best to fist measure where you lose (drop) voltage, because it does not help 
much to replace all wiring only to find out that you lose most voltage 
across a corroded ground terminal, giving you a bad return of the headlight 
current. Or a corroded relay that you can simply swap out for brighter 
lights.

Re: [EVDL] Nissan Leaf 2013 dim headlights at 14V

[Haudy Kazemi via EV]

Both sides or just one side? Not seen this myself, but if it is one side,
maybe the LED driver on that side is failing? It is a component module
attached to the headlight assembly. I think you could swap the module
between the sides to see if the problem follows the module.

If it is both sides, it could be that both LED drivers failed around the
same time, due to a common factor, such as being in the same production
batch. (I've seen halogen headlights that were installed at the same time
burn out within an hour of each other.)

[EVDL] Nissan Leaf 2013 dim headlights at 14V

Does anyone with a Leaf have dim headlights at 14V?   Do you recommend another 
halogen or change to Led or Hid lights?
