UPDATE:
I have been working on this lighting issue on and off for the past 3 weeks, thank you all for your help and ideas, I tried all of them, multiple times. But in the end I was still left with non working Hazard flashers.
I ignored the tractor for about a week out of frustration. I decided that it just wasn't meant to be.
Now I've tested the factory bulbs and the new bulbs I got several times, they do indeed work just fine, just not when you put them in the socket (I've added solder to the tips at this point still nothing) and everything in the socket worked when just testing it. hence my great frustration. I'm cleaning up/organizing the tool box when I see an old bulb from an old truck of mine, just for the heck of it I put it in the socket. I can not describe the face I made when the bulb started blinking, something like a mixture of WTF, confusion and happiness would be a close image. I take it out and put it back in, yup working, I try it in the other socket yup that one works there too. I go and get the factory and new bulbs and try them... nothing.....
again the factory and the new bulbs I got DO WORK, just not when I put them in those sockets, the base for the random old bulb I had is THE EXACT SAME. I checked, even measured with a caliper. same size same wattage the SAME SAME SAME! just way older! At this point I'm beside myself. I go and raid another bulb from my old pickup and yup put the 2 bulbs in and there they go blinking away, just like they should be.
It honestly doesn't make ANY sense and as I'm typing this I know you guys are going to think i'm off my rocker but honest to god, they work great now, no problems. I have no idea why that is, but atm I'm too afraid to really try and figure it out. I'm just THRILLED that they are working now.
Just in time too! they are calling for 12-24 inches of snow over this weekend, why old man winter why? So I will get to put them to good use when I'm by the street.
Thank you again EVERYONE, all the ideas you gave me I tried! Nothing about that issue made sense, and I truly appreciate the ideas you sent my way. I will get a video of my Hazards working and show some other lighting improvements I've made on the tractor soon.
(tom, it is mostly insulated, just not in that corner and above the garage door yet, I ran out of time to get that done before winter came sadly, and have been swamped with other projects, but 85% of it is and MAN does it make a difference!)
