My low beams have some strange streaks in the lighting pattern. It is a rebuilt 06 Tundra. Had an 04 tundra before and didn’t have these, just even light. Just put new bulbs in. Any ideas? ![IMG_4337](https://global.discourse-cdn.com/cartalk/original/3X/3/4/349938b226114e162fef551ed3ac0752b6f0a585.jpeg) ---

poorly aimed headlights or low quality headlight housings, maybe both. ---

Can’t speak to an 06 Tundra, but I usually have to re-aim my (older) vehicle’s headlights after replacing the bulb. Fairly simple job. I’ve never noticed them off that much though, the aim usually just need to be diddled a little. Did you switch bulb technology, from oem to LED’s for example ? You might want just install another new right-side bulb, its aim looks way off. ---

Are they the original OEM bulb type or aftermarket? If aftermarket, there’s your problem. And yes, streaks are very annoying to the eye. ---

Not LED bulbs, I hope. ---

I have found that aftermarket, affordable headlamp assemblies are a net gain over old worn originals, but they do have extraneous light that the OEMs do not. I stick with the bulb number that is in the owners manuals, usually going with Silverstar. ---

Yes it was the same with the old bulbs. Going to adjust the lights today I think they are point too far down. ---

It looks like the right headlight beam passes over the left, the headlights are not aimed straight ahead.
