Just a note on longevity of the increased output H4 bulbs. The extra performance ain't free. I just replaced the two Philips +50 bulbs I installed last year (about 10,000 miles). The OEM ones were 3 years old.(about 24,000 miles) FYI. The Philips did put out more light.
Interesting that they both went within a half hour of each other yesterday. I guess that supports the common "replace bulbs in pairs" advice. Which I did after stopping at the nearby NAPA which had only one option for me, something called H4BL 'bright lite" (something like that). Wagner brand I think. At least they were cheap, maybe $12 each.
I'll be calling Murph to get some silver stars or more Philips. I don't want to be caught out in the boonies with both headlights going away on me. Another good reason for auxilliary lighting- glad I have some Hella 550s out front.
Still a PITA to change those bulbs, especially the right one. Yikes.
