This is a difficult question for me to help with here myself.

I will open your question up for others here to see if someone else can assist further on this as there may be others here that may have more info on what to check or do with this issue.I hope you can get this resolved with ease.No need to reply to my last post here unless it is a last resort as it will keep your question locked to me and others will not be able to view it.If you feel you want to continue to work with me on this feel free to reply at any time but keep in mind in some cases it can be difficult to fully diagnose or help repair this without seeing your vehicle.

Thanks Pete

Hello and welcome to JustAnswer!

If the lights are dimmer than they should be yet the bulbs are new then you have to have a poor power or ground to them. If the lenses and bulbs are new yet the bulbs are actually dim then the only possible cause is not enough current flow.

What specifically was done to check wiring?

Customer: replied 2 months ago.
Checked ground n power had 12 volts on hot side n zero on ground side tried 2 different bulbs they r bright but can't seem to get the bulb to shine in the right direction
Expert:  sprinkles08 replied 2 months ago.

What needs to be done is voltage drop test the power and ground while the lights are turned on.
