Solved Broken reverse light textures

In fixing the rear glow maps of my van (which I'm proud to say I did) I managed to break the reverse light textures. I've checked over and over again and can't work out what I've done wrong. Please help

 

Thanks but how do you open the console? I can't find anything that tells me how

 

press: ~

 

Nothing

 

Apostrophe worked for me. Now its open it displays the issue, what now?

 

Here

 

Same as the official. The taillights are identical (and used to be textured). I’ll check the material.cs later today. Thanks

 

Solved, thanks @Nadeox1

Original:
singleton Material(van_reverselight)
{
mapTo = "van_reverselight";
};

Fixed:
singleton Material(van_reverselight)
{
mapTo = "van_reverselight_R";
};
singleton Material(van_reverselight)
{
mapTo = "van_reverselight_L";
};
