| Hey guys I just installed led lights in my 2-70 white. They seem to have a bit of a flicker though. Do you guys have any thoughts why this is? |

possibly a bad ground. 'flicker' may be caused by vibration ,say two body panels bolted together. a little corrosion and the power gets interrupted...on/off..on..off... Best 'ground' is the negatve of the battery, so run the -ve of the LED to there. other possibility is a faulty on/off power switch for the LED light. If old, it may 'bounce' internally and you'll see 'flicker'. Old incandescent bulbs have a 'huge' time lag and oour eyeballs can't see this 'flickering' occour. LEDs are FAST to turn on AND off and that we can see. So if this occurs, replace the switch. 3rd possibilty is that the LEDs are 'defective' though rare. Maybe a bad solder joint inside. To test power directly from the battery. IF you get flicker...gotta be the LED.

This flicker is occurring even with the tractor off. I highly doubt a bad ground seeing as the old lights were good just old and dull compared to the modern led |

| I should also say I replaced the two front lights with led bulbs. Dad suggested I try a new led and an old incandescent bulbs side by side. Possibly there isn't enough resistance in the circuit to make a led work correctly. Well when I done that the flicker was gone so I thought. After watching it for a minute and feeling proud as a peacock the led started flickering very quickly. |

hmm.. do they flicker on just battery power or do they flicker when the tractor is running? If they're fine on just battery and flicker when running, then it's probably it's noise from the charging circuitry. If that's the case, adding a filter capacitor across the genny or alt. output will fix it.

If they only flash when it's running could be caused by vibration and a bad ground connection somewhere. Or a flashing LED could indicate your alternator is putting out pulsed DC,.. maybe a bad rectifier diode in the alternator. Not the first thing to check but it's possible. |

So far they just flicker with battery power. I haven't started it yet to see what will happen |

Is it cold out? Friend put some in his barn and they flicker when it's cold. ------------- D14, D17, 5020, 612H, CASE 446 |

The reason why they're flickering is much simpler: The LED draws only a small fraction of the current of an incandescent. As a result, it doesn't take much contamination in a connector to cause it to have problems. Your LED lamps are BULB REPLACEMENTS, which means they plug into the existing sockets... ones that've been used, and exposed for years. PRobably have rusty steel springs inside the bases 'n stuff... which is perfect for causing just enough disruption in current flow to keep the LEDs from running constantly. Take the LED bulbs out, scrub the HECK out'a the sockets, and replace the LED bulbs... they'll work just fine for a while, then the corrosion will return, and you'll hafta clean it again. Reason there, is that there's two different types of metals in the contacts. Dissimilar metals become a corrosion point, and a DIODE... a SEMICONDUCTOR of sorts. You can slow this process by applying dielectric (insulating) grease to the lamp base and socket- it will help exclude moisture and air, so that your cleaning opteration lasts a WHOLE LOT longer. Any other connections through the machine (i.e. if you're using the chassis ground, like the original lamps), it'll be same for all other bonds, just like the socket. My preferred method, is to run ALL lamps with two-wire (red and black) and bring the negatives back to a really good return point (battery, as noted above). Saves lots of these headaches, and a few others too. ------------- Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem. Citrus hand-cleaner with Pumice does the rest. |

| was talking to sum buddies at coffee yesterday AM, they have mounted LED light bars to some of their vehicles, but had problems with the light switches, kept having to replace them a lot. finally one dude said he bought an old style dimmer switch, the kind that used to be on the floor of vehicles. (some of you young'ins won't know what i'm talking about) and they use them for turning the LED bars on and off. oh...and if you do this, ask anyone at the counter at O'reillys for one...you'll laugh all day! |

| Sometimes it happens with these bulbs. Unfortunately, I had a similar experience and thought it was a big problem. I thought they might become less useful in the future, so I decided to change. It happened again later and the new ones did the same thing. My friend says he didn't have this problem he has http://https://www.vont.com/product/smart-strip-lights-led-strip-lights/" rel="nofollow - LED light strips for car interior . So now it seems like I didn't make the right choice right away. However, he's only had these strips for a month, and they may flicker later. So I can't say for sure. My suggestion: if you are happy with it and not annoyed, don't change it. Chances are good that the other bulbs are flickering too. Or choose proven ones. |

Seems lot of different ideas - most point to the driver used to power the LED - internal or external and the voltage output of same ------------- Faith isn't a jump in the dark.
