H4 Bulb Recommendations

Not into LED or HID.

Hi guys, have searched, but looking for current opinions:
Cibie's and relay harness installed.
There is a load of stuff on the www regarding bulb quality, output and longevity which you may already have read, but looking for real life feed back from our community.
Looking for ligh output (NO BLUE) and longevity. (300Tdi so some vibration).
There are the +30, 40 50 etc and high wattage bulbs and much talk of reduced lifespan, hence your feedback may be lelpfull to us.

Two recommendations:
1: Get a wiring harness with a relay
2: my bias having tried various bulbs is to stick with good old boring halogen. Hella does make a 100W halogen which is off road use only......

Yes, the higher wattage bulbs have shortened life. Most H4 bulbs have a short life to begin with. It is kind of a crappy bulb type for the reason. The newer bulb types are all much better.

Try here for some of the longer life bulbs.
