Headlights for Pete 387

I need to replace my foggy headlights on my 06 387. At a brief check with Peterbilt, I found they want an arm and a leg X2.
I've searched the internet and found only aftermarket lights for 08 and newer models. Very few used ones are available for a 06. But I don't trust the quality of the used lights. Might be the same scrap like I have already.
Big question: what did change in 08 and later models? Will they still fit in my 06? On the pictures they look the same. The only number I could find on the light is P54-6010.
Any advice is apreciated.

 

I've tried that already but it's inside and water builds up in one. Now they have to go.

 

Now an update on my lights.

I found a set on ebay for 390 including bulbs. I've ordered them, had them shipped to a parcel service close to the border. As I came along I picked them up and had them with me all week long till yesterday. I had enough daylight left to install them. I couldn't find any difference to the originals. Easy to change, just 5 nuts and the plugs at the bulbs. Now since everything is done, I can say, I got them for exactly for half of the price compared to oems.
Now I'm eager to see the result. It's still dark and I'm leaving in 15 minutes.
There was a business card attached to one of the boxes. It's only an email a dress there. But just give it a try and they might respond. It's trucklights4less@gmail. com
