ariens deluxe30 led lights

want to add led lights to front of the machine at the blower housing area where the drift breaker arms would go, have seen something on this sight before about it. any buddy have any recommendations on what light to uses and wiring? thanks

The easiest is to just convert the halogen light to LED using a special conversion bulb. For example:

https://rover.ebay.com/rover/0/0/0?m...2F303065542114

OK, had to get that out if the way.

If your thinking of adding additional LED lightbars, there are many YouTube videos covering the subject. You decide on a LED lightbar, figure out a mounting method (common places are on the sides of the handlebars, or hanging under the control panel, or mounted on the bucket using the holes for the weight bar.)

For the electrical connections, the way I would use would be to tap off the existing halogen fixture wires. (Yellow for the pos and black for the neg.)

Then a switch to turn off the LEDs so you don't shine directly onto an on-coming car (these fixtures are off-road and will blind an on-coming driver.) You could decide to use a two-position switch, up to turn on the halogen only and down to turn on the LEDs only. This would take the halogen out of the circuit and allow a larger (brighter) LED bar to be used. The designation of the switch is 2P4T which means that it is a "two pull" (each AC lead) and "four throw" (2 wires going to the original halogen fixture and the other two going to the rectifier.) You can also get it in a center off if you didnt want any lights on say during the day.

I think that the Ariens OEM bulb draws 20 watts, (I believe that the Ariens OEM bulb is the same as a Sylvania 881 halogen bulb, which is 7 watts brighter and only costs $7), so if your considering using a lightbar(s) of more than 10 watts, I would use a switch to switch off the halogen. Running both together may draw too much current from the engine.

Note that you will also need to convert the electrical current. The current being produced by the engine is AC (alternating). Alternating current first flow in one direction, and then reverses and flows in the other.

The LED can't operate off AC current. It needs to be converted to DC or direct current, like a battery with a dedicated positive and negative terminals. To do this, you wire in a device known as a rectifier. The most common is called a "full-wave, bridge rectifier". Here's an example of one:

https://www.amazon.com/dp/B0002FRBZ0..._VryKDbDZMNZHD

This will produce a "full-wave, pulsating current". The current will be direct (with dedicated positive and negative terminals) but pulsating, that is, turning on and off at 30-60 times a second. To smooth out the pulsating, you must wire in an electrolytic capacitor. I would probably use a 470 uf electrolytic cap for this, example:

https://www.amazon.com/dp/B00HYQB9V2..._mByKDbQ5YFP7A

The value isn't really critical, but you must maintain polarity. (If you omit the capacitor, the LED will function, but flicker when the engine is running below top speed.) (As the frequency is so low.) Positive on the cap to positive on the rectifier. Neg to neg. Wires in parallel with the load (lights).

The function of the capacitor is to smooth out the fluctuations between the peak voltage and the nil voltage. (Like a water tank that fills when the flow is heavy and drains back when the flow is low; only with voltage.)

At this point I will mention that you can simply buy a 12 volt regulator rectifier designed to work with lawn tractors and while these devices both rectify and regulate the voltage to 14.5 volts, they are designed to work with a battery. The output voltage will be higher and pulsating, so you will not gain anything by using these in a non-battery snowblower environment. Many of the cheaper ones are half wave which will only provide around 8-10 volts and considerable flicker. If you go this route, make certain the rectifier is full-wave.

So this should help in getting you started. Start by watching YouTube videos on tbe subject and the rest should become clear.
