Default Headlights Roadtrek 200 P 2002 Chevy

Having just returned from a 4000 mile trip, I have uncovered a LOT of items that need attention in my 03 200 Popular (Yes, it's on a 2002 Chevy chassis).

One of which is, the headlights. I would like to replace these headlights with brighter ones. Preferably LED if available or at least brighter bulbs. I don't want to NOT use an HID system.

There appears to be 2 versions of Chevy Express headlights. Individual (separate low and high beam sealed beams) and composite, (Lo and Hi integrated in a one-piece mount, with separate bulbs). The RTs have the latter.

While staring at the vehicle in the dark, they appear to be sufficient (IE to oncoming vehicles), however they do not light the way adequately at night for driving. Note: This chassis has DRLs. They are always on when engine is running. They brighten slightly when turning the headlights on as they should. They are just not bright enough when on.

I have tried adjusting them pretty much by trial and error. Does anyone know of a proper procedure for adjusting them?

So the question remains, does anyone know of any aftermarket headlights available, or any means of brightening up my nighttime driving while still remaining legal.

Attached is a pic of my headlights,

Thanks.

I replaced mine with aftermarket units. The fit of these was problematic. The bracketry did not match well at all. I was able to get on to fit, the other I had to disassemble the old assembly and use the old brackets on the new housing.

Another note, I have a voltage drop of 1.25 from the battery to the headlights. This is a huge drop in relation to light output. I was going to put in a relay system to get battery voltage to the headlights but was flummoxed by the differences in the wiring diagram and my actual wiring on the van. Mine is an '02 200.

I thought of putting in LED bulbs because they have a wide operating voltage range but got lost in that rat hole of different styles and results. I pretty much do not drive at night so I pretty much just blew it off.

I have a newer model Chevy Express ('2011 chassis) with different headlight design but I agree they are poor, so I too just don't drive at night whenever possible. I realize a lot of the problem is my old eyes.

I put these in my Ď01 Dodge Pop. Made an amazing difference! Tried the brightest Sylvania bulbs and still sucked. These LEDs are great. Plug n play. Iím sure the company makes them for Chevy. Only about $50.

PJW - Thanks for the post. It could have been written by me! I've had the same question for years. Did a bit of research but just ended up putting "brighter" bulbs in. They helped but not much. The lenses are in good shape, not hazed over so I know it's not that.

If you find a solution please let us know.

John

I have a Roadtrek 02C200P. I replaced my bulbs with SYLVANIA h11 SilverStar UltraHigh Performance Halogen a couple years ago and I love the results, they ar far brighter, These are available at Wal-Mart and Amazon as well as most auto parts stores. I also use the same for my Volvo. I do not know how people see with the standard bulbs!

I replaced mine with aftermarket, what a mistake. My original ones, 08/09, were all scratched and looked like crap. I should have spent the extra money. Also, the fit was difficult and one of them leaked right away. (The clear caulk was bad) BTW, they both leak now, and have within 30 days.

Update: last week I pulled the trigger on a set of Sylvania Silverstar Ultra 9005 (hi) and 9006 (low) bulbs. A bit tricky getting them in, but I did it.

Kind of hard to tell as I only made quick trip around the block that night, but there's not really a big difference. For $86 I had hoped for a much bigger improvement. Maybe I just need to get out on the highway for a road trip again. The ones that were in there were OEM Wagners.

The lenses are in good shape. They're glass and not scratched, pitted or faded.

That is not surprising to me, as it seems to be the common result for most people. The "brighter" bulbs at a much higher price appear to be today's version of "snake oil". I have been changing out all the bulbs on the exterior of my old Buick as they badly mismatched for brightness, including the headlights, and tried a set of the 30% brighter ones which cost more but not as crazy more and they don't seem to be any brighter either in my garage only test to this point.

As a previous poster stated, you need to measure the voltage at the bulb with the engine running. Full voltage should be around 13V. If it's below 12V then you should consider installing a relay. It should be powered directly from the battery and triggered by the headlight circuit.

HBoy, I thought about those, but in the Chevy engine compartment there is not enough room for the heat sinks to stick out. They'll conflict (hit) the battery.

@Rock, I don't think it's a voltage issue, but in all honesty, I haven't measured it. I would think for the measurement to be of value, it would have to be measured "under load". I am not sure there is any room to "pierce" the wire with a test probe. They're pretty well covered.

Also, don't forget, being a 2002 chassis, it has DRLs. Lower voltage when the switch is off.

While under full load would ideal I pulled the wire off of one side and checked mine to find it had dropped about 1.5 volts. I can only assume it's worse with both sides lit up.

I actually had to drive at night last week on a desolate back road. We got rousted from our "secret" boondocking site less than 100 yards from the Gulf shore near Carrabelle, FL. Wound up dispersed camping in Appalachacola National Forest about 30 miles away.

Maybe I will wire up a relay and fix this problem...

I put these in Amazon and it said they did not fit the 2002 Chevy Express 3500....?
Maybe I should try Autozone and see what their database says....

Hi Juju,

I can tell you with complete certainty that the bulbs pictured below fit my 2002 Chevy Express cutaway chassis under my Roadtrek. Hopefully this helps you.

I think I can say, with quite a bit of certainty, that the placebo effect is a big factor in the evaluation of headlight brightness. Night to night, even hour to hour, conditions vary so much it is very, very difficult to get accurate information from observation. I have tried to do it and been very conflicted each time.


The only way I can think of to get reasonably accurate results would be to pick a moonless night so light direction doesn't change, and then go to the same spots on a route and check to see how landmarks are illuminated before and after the bulb change. Do it sitting still, not moving, as things change too quickly when moving and picking a reference distance gets nearly impossible.


My, admittedly rough, tests have shown that .5-1.0 volt of of voltage change at the lamps will change the illumination capacity considerably more than the more expensive bulbs. Of course, others will disagree, but that is fine with me.
