For anyone that put led bulbs in the amber signal /hazard lights on a current model bx80, did they hyper flash needing a resistor or different flasher relay?

Not in a BX, but my L4060 led conversion did not require anything additional. I have no doubt requiring a resistor is a thing in some cases, but across (3) tractors, and (4) road vehicles I've never needed anything additional.

I put LEDs in for headlight bulb replacements in our BX2200. They work fine as-is. No other changes. Of course there may be many kinds/varieties of LED bulbs but if they are specified to be 12v and fit the socket you won't need anything else. Plug in and go.

I've done headlights and tail lights but never tried signals. I'll give it a go. I know in some cases it isn't enough load so the flasher hyper flashes instead of the normal speed. One way to find out.

I suspect the flashers will work ok. Not counting the led headlight conversion I shaved off 11 amps of load using led bulbs in my running lights and flashers. With incandescent lighting, added front and rear led cab lights, and cab window defrosters I was way too close to the alternator's capacity.

I am adding a light bar front and rear but that isn't a lot of total draw. Probably 8 amps. I can certainly offset a lot of that by going to all led on the other lights. I'll just buy them and see what happens. It isn't a very big investment.

I put LEDs in the blinkers on my BX2230 and they work fine. I believe the flasher unit is electronic and doesn't care what type bulb it is flashing. The schematic shows a flasher unit, no separate flasher.

I have had problems with LED bulb bases getting hot and melting plastic light housings. Any suggestions?

Do you have a canopy? This is what I did on my bx2680 for lighting.

Fantastic light coverage! Total load is 8amps measured.

Better bulbs? Higher quality bulbs are typically more efficient so less heat output, there are also some that have external heat sinks to get the heat out of the housing.

I have the dealer installed cab but not with the added lights so I'm installing them myself. Thanks for the picture. I think I may have ordered similar for the back.
The rear are Nilite's off Amazon, hard to beat for $13 a pair! Fronts are about $16-22 a pair

How do you measure the load on LED lights? Thought I would add extra lights but don't want to overload the 10-12 amp circuit.

An amp meter, but I recently bought one of these https://www.harborfreight.com/30-amp-fuse-slot-circuit-amperage-draw-measurement-tool-70079.html and find it incredibly useful.
I've been using it to track down a parasitic drain on my dads truck but was curious what the actual draw was on the new work lights.

I've got the same exact lites you do, I had the longer ones bolted on a home made bracket on my loader for 4 or 5 years but never got a chance to hook them up, lol. One oem bracket did break from the vibration and I assume a branch or two. I have a box of 10 of the small ones to go on different machines.
I'm looking to to put a canopy on both the tractors but can't find a longer one to cover the back more. Going to camera's soon and want a dry place to put the monitor.

For those that don't know, LED lights do put out quite a fair amount of heat believe it or not. Either at the "bulb" end or at the base.

Something you may run into is the lens on your vehicle/machine -may- not filter the light the right way, so your red lens with a white LED may show pink or even a whiteish light. This is mostly on the older vehicles as the new ones are going to LEDs more and more anyway. That's why it's suggested you put a red LED in a red lens, amber LED in an amber lens, etc.
Just a very broad explanation of LEDs, LEDs put out something like 98% white, or red or amber light, and normal lites put out 75% of the white, red or amber light, the rest is a combination of the other colors.

For my tractor, LED's are a direct swap. The hazard and turn signals are probably 3X as bright in daylight; retained normal flashing.

I swapped all signal / flasher bulbs to led this morning on my BX2680. All flashing functions work as normal. There isn't any hyperflashing. Certainly brighter than the original 1156 and 1157 incandescent bulbs with less draw.

to move to LED bulbs you need a LED flasher. I did that to my tractor and to one of my cars. otherwise the y won't blink due to LED's don't put enough load on a regular flasher to activate it. you can get a LED flasher from Amazon

Some users have reported melted wiring on vehicles replacing bulbs with LED's.

I've experienced that on any older car. I did change them all on my Kubota BX2680 and no issues. The factory flasher unit works fine.
