Rob:
I'm assuming you've got a later model vanagon because you mention driving
lights and brights as a separate unit.
After updating my headlight circuit with relays I purchased and installed
the following replacement bulbs and have been very pleased with the
result.

Part# | Desc | Units | Unit Price | Total Price | Vendor

HL78179 | 9004/HB1 100/80w Replacement Bulb | 2 | $10.75 | $21.50 |

HL78140Y | H3 110W Yellow Star Replacement Bulb | 2 | $8.06 | $16.12 |
