General FAQs

Frequently asked questions
Do you use LED diodes or LED bulbs in your lighting products?

Peterson Manufacturing uses LED diodes, not bulbs, in our lighting products. The diodes provide a more energy-efficient and durable lighting solution compared to traditional incandescent bulbs. 

What is the difference between molded plugs and assembled plugs? Ex. 817-49 vs. 417-49

An assembled plug features a 2-wire hard-shell, weatherproof plug terminated with two .180 bullet terminals, while a molded plug has been taken one step further and features additional overmolding for an increased defense against moisture intrusion.

What are the LED versions for your incandescent lights?

Please see the link on each individual incandescent product page that will direct you to the LED version.

What is the difference between a PL3 plug and three pin amp connector?

We have a page for just that kind of question! Please see our page dedicated to the different types of connectors for further details so that you can determine the right one for your use. (Link)

What is each color wire for on my light? (common red wire , black wire, white wire)

White is ground. Black is power – low function. Red is power – high function. (Interesting note: The trucking world is different from the automotive world, where red is power and black is ground!)

Some of your incandescent lights have a different connection that I am not familiar with. When I look at the back of the light I see a pair of round wire ports. What do I do?

Each type is designed for a secure, moisture-resistant fit with the right harness. You can find a breakdown of the different connector styles and which one you’ll need in our Connector Guide

Why do I see different letters in front of the part numbers when I look on your website?

These letters refer to different levels of packaging. V=Visqueen packaging or “Viz Pack” is a hard plastic clamshell packaging for our individual products intended for retail applications. P=Poly Bag is for those products packaged individually in a polyethylene bag for protection during shipping, storage, and retail display. M=This product is sold as part of a large quantity bulk pack instead of being individually wrapped or boxed.

Are LED tail lights brighter than incandescent tail lights?

LED lamps typically appear brighter to the human eye because the LED lamps emit a narrower range of color light where as the incandescent lamps emit a broader range of color light. The actual light intensity of LED or incandescent lamps (with the same function) is generally about the same.

Can a 5000 flasher be made to alternate?

No.

Is the 570 two prong flasher a heavy duty flasher? Is the sound this flasher makes when it operates louder than standard Trico or Buss flasher?

The term “Heavy Duty” when referring to flashers typically means being able to operate more lamps and higher currents.

      Examples:

           554 & 557: 10 lamp (21 Amp) Standard flasher

           570 & 571: 12 lamp (25.2 Amp) Standard flasher

           573 & 574: 16 lamp (44.6 Amp) Heavy Duty flasher

           576 & 577: 20 lamp (45 Amp) Heavy Duty flasher 

All of these flashers do generate a sound when they operate because of the sound the internal electromechanical relay makes when the relay contact close. The intensity or decibel (db) sound level of the noise that these flashers make has not specified, quantified or defined.

An all solid state flasher like the PM 5000 flasher operates without generating any sound or noise.

 I have seen some flasher data sheets from companies like Hella that do list a sound level specification for some of their flashers. The PM flashers are not rated with this type of specification.

Does the 500 turn signal switch have an automatic turn signal cancelling feature?

No, the 500 switch does not have automatic cancelling feature.

What pattern does the V530 provide?

The pattern provided is a “driving” pattern, this is essentially an auxiliary high beam lamp.

When do I need a tail light converter (V5410) for my car and trailer?

When your car lighting system has a separate turn-signal lamp from the brake and tail light. The V5410 is an electronic trunk connector which converts vehicle lighting systems with separate turn signals to the conventional trailer lighting system.
