Head-lights and blinkers
I have issues with my head lights and blinkers
i recently installed some led headlights light bulbs and a new oem blinker bulb and now my blinkers do not work and my head lights fully work but only go down when there on the “bright” setting
My hazards and brake lights still work but the blinkers don’t work when signaling only when the hazard button has been pressed do they properly turn on
if anyone has had the same issue and can help me ill try you’re ideas.

I had the same issue with the headlights. It's becasue of the low amp draw of the LED units. Itried the ones from Amazon and they did that. I had to get the LEDs from Vette Lights (forum vendor) that came with the ballast / resistors. Put them in and now they work fine.
Not sure about the turn signal bulb. Did you check the fuse?

You DO NOT have to install big resistors to make the lights go down. It's not a resistance thing - it's continuity. I have explained this several times as well as provided SharpLight innovations the diagram to make the plug in harness that fixes this using the closing coil of a simple relay.
The reason they go down on brights is because the module sees continuity through the bright indicator bulb in the dash. Simply wiring terminals 85 and 86 of a relay across the + & - of the driver side (just need one side) bulb wires will fix the retraction problem. DO NOT be fooled into thinking you need to buy big heat creating resistors that pull full current. Even a tiny mini bulb will work in place of the relay.
Try pushing your flasher button on and off several times - over time it starts to cause problems with the blinker function. There are numerous threads on this.

Using fat resistors that just turn current into heat kind of defeats the purpose of being energy efficient LEDs 
But I'm guilty of this because I know the standard LED halo taillights use resistors in that heatsink on the backside.

The resistors on the halos are so they can sell them as plug and play. If you have a hyperflash harness they will still blink w/o the resistor.

When I bought mine from George at Radio Flyer a couple years back he told me with the hyperflash harness you can remove the resistors. To be safe I didn't do anything while under warranty. Next time I have reason to, I will probably disconnect one of the wires. It makes total sense. The resistor just adds a huge load to the system and I am not a fan of that.

I clipped one wire on each resistor and used dual wall shrink tube to seal the wires off. There is no hyperflash with the blinkers, halos operate normally, brake lights work fine. However, the flashers now have hyperflash due to them being controlled by a flasher in the switch. I nearly had an epileptic episode
. Not exactly a fan but I only use the hazards maybe once or twice a year.
