Daytime Running Lights on the Spark EV are just the headlights alone, at full power, no PWM lowering the power.
The H13 bulbs used have no internal reflector creating the low beam cutoff pattern. It just has two filaments in different positions.
Some how the headlight assembly creates the low beam and high beam pattern from the two different filaments.
I tried the very LED headlight system recommended above and had to return it because the low beam pattern was wrong and
dangerous.
This is the pattern I got with the LED in the right and the stock halogen in the left.
As I rotated the LED in the direction of removing it the pattern was perfect but it was just about at the release position and there is no way to lock it there, so I returned them.
I have been in discussions with the seller of this LED system: http://smile.amazon.com/OPT7-Headlight-Bulbs-Arc-Glass-Clear/dp/B00VNBEBCS/ref=sr_1_2?s=automotive&ie=UTF8&qid=1438880349&sr=1-2&keywords=h+13+led+headlights
The rep says with H13's it is up to the headlight assembly reflector to create the proper low beam pattern.
He said try them and return them for free through amazon if the low beam pattern is wrong.
There are many choices on ebay, but "buyer pays the return shipping". Most of the cheap crap ships from china, so no thanks.
The goal here is: Less Wattage than the 55 watt stock halogens
(more range in theory, yeah right...) , More Lumens at a whiter color for better night vision performance
(for Real).
And Don't be Rude and Dangerous to on coming traffic.
PS, Dinoco, could you post a 'Garage Door' picture of your beam pattern?
EDIT: Has anyone found an LED H13 headlight replacement that works correctly?
