Can halogens handle bumps and vibrations? I had a halogen desk light that I could never keep a bulb in. Any little bump and poof! Plus that thing would scald anyone that dared get near it. It was bright though and I kept feeding it bulbs for a long time before finally chucking it in the trash.

I also have those halogen lights on tripods from sears. You know the ones... the super bright work lights. They make great hand warmers in the winter lol! But same problem... bump it too hard and poof!

 

Well that can be calculated to with ohms law . Power (watts) = I^2 (current) Times R (ohms) so we can figure out ohms by doing Power divided by I^2, but if your using 12 volts and a bulb with the same wattage your resistance (ohms) should be the same. But if your in doubt i think just slapping a 3.5 amp max fuse in there ull be safe.

 

Well the h3 halogens are off road automotive bulbs so i hope they can handle the bumbs lol.

 

4x4 ranger. Felt like I needed a ujoint from the way it was driving. So, I crawled under it and found all kinds of play in the axle. I figured I'd at least change the oil in it, so I pulled the cover off and before I knew what happened I had the differential out. Now its a big project!

 

I can help there i spent many uh days in my EET major rigging up led's. Just need to remember an led as 2 sides cathode and anode. The cathode should have a flat side on the led. The cathode has to at a lower volatage than the anode so basically connect the cathode (negative side) to your negative or ground. Led's run at 1.8 to 3.2 volts so make sure you have a resistor in there to soak up the xtra voltage our you will burn them things up.

When chosing resisters always use the double principal. Find out what your wattage needed to power the led's will be than double the wattage for the resistor

 

We will see if the calculations prove accurate

 

I have an 01 1500 ram Ran like a clock till the week after the warrenty ran out and BAM the tranny is dead. its been down hill since there practically everything is knew on it except the motor and the frame lol!

 

So the cathode to ground and the anode will be ok having a +v and then -v oscillation?

 

Never had luck with dodge trannies. But on the plus side dodges dont rust very easy lol

 

The exact defintion is "the cathode has to be at a lower potential in respects to the anode" So just put ur cathode to ground. and your anode to the positive (for dc). i don't know where oscillation comes into play. if your sticking them in ac power well it doesn't really matter which direction you got them in ur just gonna half wave rectify your ac.
