Default H4 to LED Headlight Conversion?

Has anyone with H4 headlights converted their bulbs to LED's? If so, which brand works?

I have H4 headlights but, as my eyesight seems to be getting older, I have a harder time driving at night.

Thanks!

To get the most out of your headlights, its important that they get full battery voltage. Most harnesses have thin gauge wires going to the headlights, couple that with corrosion that develops at the terminations on older cars, and you end up with less than full battery voltage at the headlights. If your headlights are yellowish and not white, then you probably have less than full battery voltage to them. Here is the solution to the problem: https://ceautoelectricsupply.com/hea...ht-relay-kits/

Try the relay setup first you'll be surprised with H4 getting full voltage.

These are DOT approved and drop right in. The price is each. Spendy but bright and no glare like others units.

After researching an H4 to LED bulb conversion probably would not be effective. I decided to replace the whole H4 lights to LED's. I went with Dapper's OE7's. DOT approved.

My only issue is that we had to make quite a bit of modifications to the light buckets in order for them to fit. But, once they were properly installed, I took a drive at night and I could not believe the amount of light and super bright.

I'm sure it should give my senior eyes enough vision now. Highly recommend making the switch to LED headlights if you do any night driving with your classic.

The good thing with that brand is they look "original" at least lens wise, which I like that. The ones I linked are more clear looking and not original looking at all.

Make sure to readjust your aim for the headlights on a wall to make sure they are not to high or low. The LED should have a crisper beam pattern.

That's the one, Pops! These have glass lenses and are relatively stock appearing. That was real important to me.

The modern, fancy ones just do not appeal to me. I just wanted stock looking headlights.

Yessir BO these are stock looking and even have glass lenses. Of course I had to pay extra for glass but, worth it.

Last night's test drive did seem like they're pointed a tad too high. But, man are they bright and white!
