2003 Dodge Ram 1500 Headlights and Taillights [Replacement and Installation]


Today, you will find information about the 2003 Dodge Ram 1500 headlights and taillights, reviewing the different bulbs (low and high beam) and their replacement and installation guide.

2003 Dodge Ram 1500 Headlights

If you have a Dodge Ram 1500 2003-2005, I will tell you some of the best light options for this truck and how to install them.

You need to know that this truck doesn’t have the best beam pattern from the factory, and the LED lights will never fix a bad factory beam pattern.

So even with a halogen lamp, if the low beam is not good, the high beam has a lot of diffusions and flooding.

In this case, you want to find something that matches the factory glow pattern but brightens it up.

You can use a digital lux meter to test precisely how bright your headlights are, and this is the best way to measure how bright or dim a particular light source is.

Lumens don’t quite cut it for this kind of testing. So if you test with the same bulb and the same meter in the same area, you’ll get the same percentage increase or decrease.

You can test your 2003 Ram headlight, and it’s rotated about 25 feet from the wall. It’s a factory halogen low beam (180 max lux).

You can see if you have a hot spot in the middle, but it’s not the prettiest block pattern from the factory.

So your LED bulb will not fix the factory beam pattern.

Now what you’re going to try to do is brighten it up and not introduce a new bunch of glare over the boundary line.

Therefore, you will want to check the factory high beam.

Stock high beams come in at 250 lux maximum.

You can see the hotspot is not up. It will go a little further, and you will need to find an LED bulb that will emulate that.

VX (70 max lux, low beam) 

VX bulbs have a very low beam pattern.

It’s almost on the ground, and you didn’t move the lamp housing when you did the test.

When you install the bulb and note it correctly, that is what you will get if you pay money for this bulb.

If you use a type of this bulb, mount it in your truck, and drive it down the road, you will have a bad time.

The low lux bulb is not what you want to come in at around 70 lux, which is significantly dimmer than the factory.

VX (120 max lux, high beam)

VX high beam bulbs come in at 120 Lux maximum, significantly dimmer than standard bulbs.

It’s just that there’s a lot of light everywhere, no hotspots you can identify.

So it would help if you did not choose a bulb that looks like this.

Morimoto 2 Stroke (530 max lux, low beam)

The low beam on the Morimoto 2 stroke does have a different hotspot in the middle.

But there is a kind of shadow effect on the left and right.

Morimoto 2 Stroke is a very well-done bulb, and it is one of the most recommended bulbs by many.

Unfortunately, for this particular headlight, it’s not that great.

But at the maximum Lux of 530, it’s an improvement over Stock.

The 2 Stroke high beam increases the hotspot just like a factory bulb does, and it delivers a maximum of 550 lux.

But you may have a lot of shadows left and right.

So you’ll want to keep looking and see if you can find something a little better.

S-V.4 (720 max lux, low beam)

The S-V.4 low beam for bulbs comes in at 720 lux maximum, and it’s a favorite bulb.

Many people install it in many vehicles, and it usually works fine.

But maybe you have some shadow effects on the left and right.

It’s not the best choice, but it’s bright.

S-V.4 (670 max lux, high beam)

The high beam S-V.4 in this particular bulb is slightly diffused and reaches a maximum of 670 lux.

Now Stock bulb is 250 and 670 as an upgrade.

But there are many kinds of light everywhere.

GTR Lighting Ultra 2 (760 max lux, low beam)

The GTR Lighting Ultra 2 low beam comes in at 760 Lux maximum. The S.V-4 is 720 lux, so it’s only 40 lux brighter.

But you can get a lovely block pattern.

It makes good use of the headlight housing. You get your hotspot back.

It looks like a factory halogen bulb, precisely what you want.

Here you don’t pick up a ton of glare above the cutoff.

So this is what you want to choose if you need bulbs for your 2023 Ram.

GTR Lighting Ultra 2 (930 max lux, high beam)

The GTR Lighting Ultra 2 is the ultimate high beam at 930 lux maximum.

It looks great, and it increases the hotspot. It will light up the road at night.

If you need a high beam option, this is it.

Honestly, this bulb one does the best on your 2003 Dodge Ram 1500 truck out of all the earlier bulbs.
