Tried viewing in both lightroom classic and lightroom 5, both times the yellow + green sign appears heavily pixelated despite being right next to another sign which appears fine. Any help appreciated

I downloaded your file and viewed at 100%. The sign is still way too small to see an issue. However, zooming to 200% then 300% I can see pattern rather than what you describe as pixelated. The fact that there are no silmilar patterns anywhere else on the image would suggest that niether the file or LrC are the cause. My guess is that the sign has a textured or patterned coating the to make it more visble when car/truck headlights shine on it.

thanks, Ill let you know if I enounter this problem elsewhere (I have for instance noticed branches against the sky tend to be a bit pixellated too)

I've attached a section of your image at 200%. Notice that the size of the squares pattern on the green sign doesn't match the pixel size on the brown sign.

Is this straight out of camera, or edited?

The yellow/green sign kind of looks like it was painted with a masked adjustment brush with a high amount of Sharpness or maybe Texture.

Can you give more details about the image? What kind of file, what resolution, what camera took it? This looks like a compressed JPG, and JPG compression might not create artifacts as noticeable in the smooth color area of the larger sign.
