LED Lights

[Jassers]

I recently bought Hikari LED lights for my 2011 Ram 1500. The lights work fine at night but the daytime running lights don't work right. The drivers side goes out and left one flickers. I bought the Hikari resistors and installed them.  I tried swapping parts to other side but problem stays to the driver side. I checked voltage and get 8.5 volts while daylight running lights are on. 12 volts to regular. I put the original lights back in and they work fine.
I am thinking that there is supposed to be 12 volts for running lights. The 8.5 volts might be enough for the old lights but not enough for the LEDs. Now why am I getting only 8.5 volts or why aren't the LEDs working right?
