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?

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.

There are several topics on this already. Mods, please merge.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

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.
