I am able to put stuff together once provided with an example, and assume I need some type of switching device to make it so I'm not turning on dashboard lights when I open the door / blowing anything up, but, as of yet, haven't figured out what to do there. LED strips are cheap as chips, so my thought is I would just tap a 12V power supply, but then thought about it more, and technically I would want these on in 2 cases:ġ) If the headlights are on (would only have power while the car was running essentially: if the dashboard is backlit, the foot wells should be lit as well)Ģ) If a the dome lighting that corresponds to whatever area is on (in my car, there's a light in front, and another in the back, so if you open the front door, I'd want the front foot wells lit open a back door, light the under-seat lights) If the same size as a handy 12 volt lamp battery it could run the LEDs twice as long.Trying to add some lighting in the foot wells and under the seats in my car so that when someone drops something down there in the dark, it's not something that (at least not every time) requires pulling over and grabbing a flashlight to see.

Bigger distributors like Mouser and Digi-Key probably have a wider selection of DC to DC converters, I haven't looked recently.Ī 6 volt battery wired in series with the tractor 6 volt battery could supply only half the power for the 12 volt LED too. Jameco has some converters but none rated for lower than 9 volts input in their 2016 catalog. Lamp socket and LED polarity might be a problem. Designed to connect to your Pop & Lock Power Pop remote keyless. Make it easy to see cargo in your truck bed by installing this bright white LED light beneath your tonneau cover. A bit more efficient scheme is to use an isolated 6 volt to 6 volt converter and connect the floating output in series with the 6 volt power source so the converter has to handle only half the LED power. LED Light for Pop & Lock Power Pop Remote Keyless Entry Kit - 12 Volt - 8 Diode - 2,050 Lumens - PAL9135. Best if the output is isolated so the 12 volt side can be negative ground as the LED lamps expect. That requires the converter to handle all the LED power in and out. One is to use a DC to DC converter with 6 volt input and 12 volts output. Many a 120 volt LED lamp uses that switching regulator and some make so much radio frequency noise that they prevent radio reception in the neighborhood.Īs for powering a 12 volt LED from 6 volts, there are at a couple circuit possibilities. I'm beat, spent all day ,sunup to sundown and then some, 'modifyig' a modified, replacement trailer axle to fit.it's almost done and I KNOW my back is.off to the shower.Ĭhecking a catalog from Jameco ( ) I see high output white LEDs have voltage drops of 2.5 to 5 volts, so it would be easy to make a simple 6 volt lamp replacement with either a series resistor or a switching regulator. When I get time, I'll try to draw some 'pretty pictures' and post.
Most DC-DC converter 'modules' I've seen to far SHARE a common between the -ve input and the -ve output which is fine IF the LED has 2 leads and NOT grounded. 2Pcs H8 H11 LED Bulb 90 HB4 Led Lamp Super Bright Car Fog Lights Day Driving Running Light 12V White. Isloated means the output power is 'floating' ( NOT connected ) to the input power. You NEED an ISOLATED DC-DC converter IF the LEDs are say '1157' style ,with the shell of the light GROUNDED to the tractor or truck or whatever.
These bulbs are energy saving and commonly used for Park Lights. I can buy premade modules for LESS than a handful of parts from Digikey BTW. OzLED stock a wide range of 12 Volt LED Vehicle bulbs ranging from 2.5 Watts to 10 Watts. Clear as mud right ? welcome to my world and I design these things but NOT as cheap as the off shore stuff. A 'converter' usually change voltage and a DC-DC converter changes an input DC voltage to a different output voltage. An 'inverter' typically changes polatity of a power supply to the opposite.
You actually need a DC to DC converter NOT an 'inverter'.
