Q:Wiring a relay for parking light flash on remote starter. Parking light system draws more than the output of the on board relay so programmed the output jumper to (-)200ma output (factory is positive). Question is this, I will need supply 2 12V inputs to the relay, so can they just be drawn from the same 12 supply wire from the batt? Also, parking lights draw 15 amps, so how much should I fuse the supply wire at if its operating the relay coil as well?

Sounds like the output jumper can switch the relay coil on the low (ground) side, so you can run the same 12 volt wire to power both the coil and the lights. If the jumper can only supply current and not sink current (though it sounds like it can sink current and you are all set), you will need a separate signal line connecting the jumper through the relay coil to ground. For a 15 amp lights plus the relay coil, a 20 amp fuse is the next larger automotive fuse and will protect the circuit without nuisance blowing. Just make sure the supply wire to the relay and lights is at least 16 gauge or it might get too hot.

Q:Hiya,I don‘t know if anyone knows any fancy effects that can be had with a sheet of polarizer gel, placing them in front of flashes to polarize the emitted light? I‘m used to using lens polarisers - but not on the lights - or combining them for that matter.So basically . is it practised? If so what is it useful for?

Yes, it's used. There's a chapter in Light, Science and Magic on using polarising filters on lights as well as lenses. Doing this allows you to fine tune the balance of the artificial lights against the ambient. It can help you reduce the glare of lights on shiny objects too.

Q:Can anyone tell me how to make an homemade auto mister for a chinese water dragon?

Well, I said it last time you posted this question, but if you're only misting the one lizard it would probably be simpler to just mist with a bottle a couple times a day unless you're not around. I don't know about making a mister, but would a drip system work? It can be as simple as a 2L plastic bottle with a couple pinholes poked in the bottom, set on top of the screen on top of your dragon's tank. Try to have it dripping near where your basking light shines so the water will evaporate back into the air raising the humidity. If you're still having humidity problems, you can also cover up most of the screen top with a towel or some tin foil to keep it from drying out so quick. You'll have to keep an eye on your temps though as this will usually also raise them some.

Q:I just got into my car this morning and noticed my ABS light is on. It was not on last night, so I have no idea what happened. My car sat inside all night, and like I said, when I got in and started it this morning, the ABS light was on and did not turn off the entire way to work. Does anyone know what may have caused this, and what needs to be done?

If you fill comfortable get a bike and if the weather is crazy in NJ get a car

Q:ABS light is on, what does that mean, how do i get it off, and how much $$ will it cost me to get it off (ballpark figure)?Thanks, John

ABS light means the computer senses a problem w/ abs and it has - most likely - shut down the abs returning the system to standard brakes configuration. You can drive the vehicle normally - as long as brake feel and performance is ok. Just don't expect to have abs kick in. If you start to skid - pump the brakes yourself! The most likely cause is a dirty wheel sensor, sensor out of adjustment or a damaged wire to the wheel sensor. The sensors are magnetic and over time they collect metallic particles from the pads and discs - they get furry. Clean them off. Those are fairly easy to fix and not too $$. A scan tool will identify precisely the fault. If it is a sensor it will tell you which one. If it is in the actuator - or computer those get into a lot of money - so you may just want to stay with the standard - abs off system.

Q:How to write a safety declaration for the performance evaluation of automotive lighting

Far away, do not hurt the eyes, long life, not astigmatism, wiring is simple, not broken line, the annual inspection 99% clearance, auto repair factory partners.

Q:Ford Expedition, ‘99.What does that mean?My car stutters a little when the Service Engine light is on but doesn‘t when it‘s just the ABS warning sign. They‘re never on together at the same time. Why?

service engine light is telling you there's a fault in the system,ie., map sensor/map sensor/tps/oxygen sensor(s). abs light depending on color, I assume it's yellow mean's there's a fault in you brake system. the stutter in the car sound's like an oxygen sensor.

Q:Do I need to get it fixed, Is there something wrong? What kind of price am I looking at? Im under warranty

There are little balls in the wheel well that help keep the balance of the tire even. After driving on the same tires for a while, the balls can move around causing it to become unbalanced. You have to have a special machine to have them balanced, so you should take it to a tire shop. It's generally very inexpensive.

Q:I currently own a D3200 which has difficulty focusing in low light conditions, and I‘m thinking of upgrading to a semi professional camera.

No matter how good an AF system is, when light is very low, it will fail. That is unless you're using infrared. The D850 has no low light focus assist lamp. To use a feature like that, you will need a Nikon flash that has its own focus assist beam.
