Re: UPDATED- LEAF LED High-Beam upgrade

Fri Jun 12, 2015 1:16 pm

The bulbs I purchased were 3600ML each for a total of 7200ML.
I purchased them from E-bay http://www.ebay.com/itm/251920005757
The seller was autobase-us and they shipped quickly for under $70.

In response to the second last post - would an adjustment of the DC-DC voltage converter be a less intrusive and expensive task to bring brightness of the high-beams up (say to 13.8 volts)?

That seems like a bit of a hack, and could raise other issues. AFAIK, the converter is controlled by CAN, so could be quite a task and not necessarily inexpensive to change. I guess you could spoof the voltage sensing and fool the converter somehow -- a worse hack, but unsure how high you'd have to make it. There could be implications for the 12V battery and all other systems on the 12V bus. Probably easier to wire in a separate DC-DC converter to boost the 12V battery voltage for headlamps only. The converter will put out heat, need careful choice of mounting location, etc... Really, by the time you go to that trouble I think a relay and some heavier gauge wire is still the easiest cheapest and safest route to getting higher voltage to the incandescent lamps.
I noticed you're still working with polymers.

Just as I was ready to purchase this the seller went out of stock on H9 bulbs! :twisted:

I asked the company on the main listing about stock. I have seen some complaints about HID and the dispersion patterns. At this point i seems no one cares because anything is better than the high beam that is currently there. How MUCH POWER DOES THE CURRENT BULB USE vs the led or hid?

From the OP: The LED high beam assembly draws 30w, needs 2.2 amps@ 12v, and has a color temperature of 6000K.

An easy way to test that would be to spoof the battery temperature sensor, which is integrated into the battery current probe out on the 12 volt battery:

According to the manual, Pin #43 of the VCM is sensor ground, connected to Pin #3 of the battery sensor, and Pin #50 of the VCM is an NTC thermistor output, connected to Pin #2 of the battery sensor. If you were to cut the thermistor wire and insert some extra resistance, the VCM will think the temperature has dropped and turn up the charging voltage. I'm not sure at what point the VCM will throw a code for an open thermistor, but according to the manual the acceptable voltage range is 0 to 4.8 volts DC.

Sounds like the seller will have some stock next week, while doing this I also plan to replace the parking light that's right next to the high beam. Do you guys have any recommendations on which bulb should I get? I saw a lot of those W5W/T10 LEDs online but I just need some feedback about a quality one.

I would advise against replacing the turn-signal bulbs front or rear, because the turn signal lamps are monitored by a "bulb out" circuit, and all of the T10 LEDs bulbs on the market today will trigger a bulb out event. This is because of the low current draw of the LED bulb fools the monitor circuit into thinking that the bulb is defective. The only way to avoid that is to bridge the bulb power lines with a large resistor to fool the circuit.

On B-platform cars like the LEAF, a bulb out event is indicated by a rapid blinker relay sound (which is artificial) instead of a warning message.
