LED Question

I changed my map lights to LED w5w bulbs all the other bulbs I changed work fine... The map lights when not on are pin point lit...I tried other bulbs(got a ten pack) and same thing. Any ideas? Will this drain my battery the light given off by then is so minute it almost not noticeable but I don't want my battery to die...any suggestions? Thanks!

I noticed this issue with mine, I can't imagine the drain being large enough to cause the battery to die, but I could be wrong.

Its unlikely to cause any issue with battery drain. It only takes around 1 milliamp of current to dimly activate an LED. The acceptable range for parasitic leakage current is at least 10milliamps. Quite possibly the LEDs have a lower leakage than the incandescent bulbs you replaced. If you really want to know for sure you would need to jumper in a milliamp meter in series with both the original and new to compare the currents. Like all the MINI lights the computer turns on the actual current, the switch just tells the computer which light to activate. So the computer output is a transistor, which unlike a true mechanical switch always has some leakage current. The transistors were designed to carry several amps, whereas the LED replacement is probably less than a tenth of the same current when full on.

I have the same issue, ur not alone. I changed all except the map lights. I don't like them being on even if it's just a wee bit.

Mine do it.

It's part of the pre-run circuit. Your LED in the push to start is on the same circuit.

It powers off after about 15 min.

Not a power drain issue at all.
