High quality, but incandescent with yellowish tint.(2700k)
Am substituting Dr. LED 8 chip T-3-1/4 (T-5) lamps to achieve brighter white light (over 180 lumens) and decreased power consumption..
Profile of LED and incadescent bulbs is comparable..so LED bulbs will fit. 8 LEDs: 4 high brightness Cree LED chips on each side of circuit board.. non-polarized and circuitry maintains uniform brightness from 10-15VDC ( or 12VAC input), i.e., a constant intensity at different voltages. The flipside
The LED Bulbs appear brighter..in fact am able to discern illumination in bright sunlight..

It is not advisable to switch to a brighter, whiter light for daytime running lamps. Reduced visibility and safety will be a concern because other drivers won't be able to distinguish the car moving towards them in the distance, that's why the DRLs are an incandescent more yellowish color for the reflective housing.
It would be different if you had a dedicated LED DRL assembly as it would be more directed and focused, but placing an LED bulb in a halogen assembly will not achieve a better result.
Those 5W bulbs are not daytime running lights. They are the front parking lights which are also referred to as position lights and city lights in Europe.

OK. The dealer was unsure of their title so selected one.
It appears they operate when the vehicle is running...
Now 1W LED bulbs that offer 10W incandescent equivalent light output.

The bulbs replaced are minor T-3-1/4
5W incandescent bulbs...
Apparently mistitled as driving lights, but replaced both of these inoperative 5W bulbs several years ago with dealer parts.
The glass envelopes were blackened.
Now they are LED's.
The two other bulbs perform the heavy lifting.
Feel free to survey yours and replace as you see fit.
Most are probably blackened or burnt out after 20 years.

So if you did a test where you positioned the car say 300 yards away and ran both the incandescent bulb and LED bulb, would the LED have the same if not greater output? And it wouldn't blend in with the surrounding environment in bright sunlight?
If it produces a white light that is still visible, I'm all for upgrading the 20 yr old bulb I have in there now.
2 incandescent bulbs X 5 watts = 10 watts.
2 LED bulbs X 1 watt = 2watts.
10 watts - 2 watts = 8 watts energy savings.
8 watts ÷ 12 volts = .666 Amps.
Now if I could find 10 other places to reduce power consumption.
Instrument cluster, radio and climate control bulbs come to mind.
The challenge is working the LED bulbs to achieve uniform light output or dimability (The Dr. LED bulbs featured here are not dimmable)
On information, certain radio and or climate control bulbs are 8V....
Do all 98 on have em? Guess mine are blown? Personally I would go with yellow/orange as a choice.Better contrast vrs perceived reflection? Who knows. Cool topic anyhow.
Do they function like DRL,key on,lights on?

1998-2000 headlamp assemblies feature this third, albeit minor bulb.
Still trying to wrap my head around the title of parking lamp...as it appears they operate when the car is moving...
Order a set from Dr. LED and report your findings. ..
The rear tail light assembly each have a T-3-1/4 bulb-replaced mine with red LED's
The front side marker lense bulbs were replaced with amber LED's
The 4 Door Pocket lamps were replaced with red LED's (red is easier on eyes at night)
The Trunk lamp was replaced with a white LED...huge difference
All Dr. LED - marine rated products.
Was going to replace my T-3-1/4 license plate bulbs with Dr. LED, but they are too bright,
The third brake light assembly will maintain T-5 incandescents, but will supplement with a third or, if necessary, a fourth as LEDs to reduce turn on time (safety), while avoiding notchy turn off time of using straight LED's..and avoid triggering bulb out indicator.
