LED headlights upgrade worth?

Thu Nov 22, 2018 3:39 am

Hi all,

I am wondering if replacing regular headlights bulbs on a Leaf 2015 with LEDs is worth the cost. Do you think LED lights reduce battery consumption?

Thanks!

You need to put the battery consumption in perspective.

LEAF can easily travel 4 miles per kilowatt-hour of power. That is 250 watt-hours per mile of travel.

A low-beam incandescent headlight bulb will consume about 50-60 watts of power; two headlights then is 100-120 watts.

So you can see that headlights on for over TWO FULL HOURS would only consume the power for 1 mile of range. LED will reclaim only a portion of that mile.

This is a fairly minor range impact. In my opinion, if this is your primary motivation for doing the conversion then it is not worth it. You can extend range much more effectively in other ways.
I noticed you're still working with polymers.

The reason I replaced my halogen bulbs with LED is because the Leaf does not maintain the 12V accesories at 14V like a ICE car does so the halogen headlights are not as bright as they should be. My LED lights have a working voltage of 8-32V so they are never dim.

I once tried to read the back threads on LED headlights. I found that almost every LED kit link on Amazon was a dead link. Since some kits are probably total junk, or don't work well with the Leaf, it seems like a better place would be a Wiki page listing the "current favorite" kits of the Leaf owner community.

100% will reduce energy consumption and have a significantly longer lifespan

With my ICE truck, I bought someone else's LED headlamps. Er, LED bulbs in halogen lenses. Big mistake. It's not necessarily a simple plug and play. Incandescent bulb mirrors work differently than LED reflectors. My LED lights gave me little "on the road" light and blinded everyone. I could sure read street signs but not see the pothole at the pole's base. I took the LEDs out and reinstalled my halogens.

If you proceed with an Amazon purchase, make sure your LED light kits are SAE compliant.

I already have the nissan LED low beams with tungsten high beams. I wanted brighter high beams so I put in double brightness LEDs that probably not DOT approved.
I didn't do it to save power.
I did it so I don't hit a deer, mule deer or a cow, you know like moooo cow because I live out in the country.
I figure not hitting a deer is better than saving a little power.

I've found that animal warning whistles - at least the larger ones - work well enough. I live in deer country too, and worked a shift for many years (20+) that had me driving both to and from work during deer "active" hours, usually in the country. I never hit anything larger than a mouse. My housemate's PIP got did get hit by a rutting deer, but it rammed her car from the rear side, so nothing would have prevented that. The Gen I Leaf's high beams truly were terrible. I put in Philip's "X-Treme" brighter halogens, but they only made a difference in unlit areas- like the country. If I had to stick with them I'd use auxiliary driving lights tied to the high beam circuit...

I have rewired the high beam circuit to be a slave for a relay and installed 100 watt high beams on other vehicles.
That has worked really well.
