You will love your e-codes. I've had them in various vehicles since the Seventies. Hellas are indeed some of the best. I currently have Cibies, which have a bit less vertical light on high beam than Hellas. Upgrade bulbs are available, but brand-name standard 55/60 watt bulbs are very good indeed. Be sure to aim them properly so you don't dazzle oncoming traffic with your low beams. Simply make sure the flat horizontal cut-off slopes slightly down away from the truck, and that both lamps are adjusted the same. For fine-tuning, have someone drive your truck towards you at night, or follow you in your truck. Sorry for the long reply; I just think these lamps are great, and so few people seem to know much about them. Enjoy!
