clear alternative help

[speedtrip30]

I have a couple of strips of LED's not working on my clear alternative taillight. I oringinally thought they had blown but I notice sometimes a strip will flicker off and on. The blinkers work fine, it's just the red taillight. 2 strips on the outside work it's just the middle one's which play up.
Any idea's or people had the same problem?

Contact the manufacturer, you have a bad contact on the board the LEDs are mounted on.
