As of today, SCS have released a new patch v188.8.131.52 (currently Steam only) that allows the lightbar (globetrotter sign) to be skinable on the New 2012 Volvos.
As a result I will be editing my current Volvo skins to show appropriate names where needed. I have already updated Phoebe Grace and will do the rest tomorrow.
Please be aware, the update also changed things with the truck engines in the shop, meaning it is all out of order if you are using my Volvo front grill mod. I have also updated this.
