Default do headlight get dim over time?

At night, my headlights seem too dim. they work, they're just no very illuminating. I started driving with my high beam on and Iv'e never been flashed but I'm not comfortable having that little blue light on with oncoming traffic. I wondered if this is normal or something isnt working properly, maybe the bulbs wear out.

Short answer is yes, bulbs get dimmer over time. Usually not very noticeable. Try new bulbs and make sure the headlights are aimed correctly.

My driver side headlamp bulb was significantly dimmer than the passenger side for a while even though both bulbs are less than a year old. I removed the bulb, sprayed CRC QD Electronic Cleaner into the headlamp connector, brushed the metal bits on the bulb and connector with a wire brush, utilized a dab of dielectric bulb grease and both are now equal brightness. If you try this, wear gloves when handling the bulbs so oil from your skin doesn't transfer to the bulbs and cause premature failure.

If you indeed need new bulbs, replacements are super cheap on RockAuto at less than $3/bulb

I been cleaning up and greasing all kinds of connections so that makes sense to me except I get grease and oil all over. I think the outside of my gloves would have more oil than my hands inside them. For 3 bucks I think I’ll try new bulbs and a dab of grease to seal the connection. Also, I will treat one or both first so I can compare the outcome! Thanks for the good pointers!

Mine were never bright enough even after trying several bulb changes. Interior of the headlight and reflective surface had degraded. Ended up getting a set of new headlights and a new loom with relay control that runs direct off the battery. Very bright now. Some people have repainted the insight of the headlight themselves with reflective paint.

my dimming lights were fixed by replacing the bulb connector - it was warped from heat and likely had a ton of corrosion

Upgrade to better bulbs, just watch out for the 'duty cycle' on the bulbs. The higher output bulbs can sometimes not last as long. The duty cycle will be lower on those so read the specs before buying them. It will say how long they will last (number of hours) and watch the voltage rating. look for ones rated at 13 or 14 volts, they last longer.
