Changed to led lights now interior light only works sometimes and only I break light is working

Too difficult to understand.
Spell check please.

 

That was your first mistake, "Installing LED Globes",

Don't waste you "Time and Money" of LED's in Cars, that were not designed for/with them.

Been there done that, and replaced the LEDs with Standard incandescent globes.
Believe me, Standard Globes will last longer than LED's.

 

LEDs are ok. If the fronts are a wedge globe try turning them around. If the LEDs are cheap EBay ones then this could explain why the brake light is not working. Unfortunately the cheap EBay gear tends to be pretty poor as I have found.
TBH I'd probably not bother any more at $30+ a globe for an LED the cost outweighs the benefit. I have had a reverse LED fail in under 2 years and I popped a standard one back in due to cost. The other one is going the same way and it too will get a standard globe more than likely as I can't justify $70 for a pair of reverse bulbs.

 

LED are good if you buy SMD style, I don't think you can turn a brake light around as they are 2 in one. I say you just brought the cheapest set you could find. I've got SMD in my interior and reverse lights as they are much brighter, wouldn't use them as parkers or any other lighting. My reverse have been in for 10 years but I don't drive in reverse to often. If they flickering either its not a good connection or stuffed diode in the led.
