Default daytime running lights

Hello all,

I was wondering if anybody knew or attempted to put a switch on the daytime running lights so that they could be turned on and off as needed....or even how to disconnect them all together. My reason for this is when I go to work in the morning some days it is better to see with just the fog lights on.

Thanks

If you turn on the Parking lights the running lights go off.
So... Turn on the parking lights and Turn on the fog lights.
This way others may be able to see your rear also.

Pulling the parking brake one click will turn off the daytime running lights and won't set the parking brake if it is adjusted correctly.

Actually, the parking lights will not turn the DRLs off. I wouldn't recommend the brake lever approach as there is a possibility that you will overheat your brake system.

I don't like the DRLs, so I pulled the DRL relay (on an LS, it is within the underhood black box). This was okay (everything worked fine) except for the high beams. Only one high beam worked!

I will be trying to figure out the relay wiring so I can run a jumper wire for the high beam. That way I can have all the lights work the way I want them. I find the DRLs very annoying when I see them on other cars.

I will try to find that relay for the DRL on my saturn (97SC2) and hope that both high beams will work. I agree....daytime running lights are annoying because in all reality they are high beams! At least saturns aren't like some cars where there's a computer which even determines when to turn on the regular driving lights!

You can order DRL overide units from Galls Inc. They sell to police and fire but most items do not require you to be a police officer or firefighter. The web site is www.galls.com

I couldn't fid the overide on thier web site but it is in the catalog and if memory serves runs between $40 and $60.

Maybe its just me but I have had more people pull out in front of me with the DRL than I ever did on my old 93 Eagle Vision with or without headlights on.

Do the DRL turn off if you turn on your normal nighttime driving lights (NDL)? Because if the DRLs are like high beams, I believe it's not allowed to have high beams on unless you're on a deserted stretch of road (hmm...reminds me of some B horror movies

I don't have my L-300 yet, just wondering, as I haven't owned a car with DRL before...

Bryan, and others,
Yes, the DRL's are the same physical bulbs that are used for high beams. However, those bulbs are not high beam when in 'DRL-mode'. The bulbs operate on reduced power (30-50%) when operating as DRL's. When high beams are turned on, they use 100% of their power.

The best way to see this for yourself is to either place a mirror in front of your Saturn, or have someone switch between high's and DRL while you stand in front. I'd suggest wearing sunglasses first and not switching to normal nighttime lights in between. Going directly from DRL to high beams will give you a better understanding of how bright DRLs really are. At night, if you play with the 3 different light settings, you'll notice that the light intensities do differ in all three modes. (Yes, I've done this all due to idle curiosity).

Finally, my DRLs have been useful at night. During heavy snow storms, under very specific circumstances, the DRLs give better visibility. This is because there is enough light to light my way, but not too much light shining back off the snow.

Ultimately, have fun in your Saturns, no matter what you decide. <img src="http://www.saturnfans.com/cgi-bin/UltraBoard/Images/Happy.gif" border="0" align="middle">

well i attempted to remove the DRL relay and as expected the left high beam did not work once i tried to put on the high beams....it seems saturn figured people would attempt to remove the relay to disable the running lights and to discourage this they wired the high beams through the relay. Now does anybody out there know how to read a schematic? My haynes manual has wiring diagrams and if I could figure out which of the contacts on the relay carry the current for the left high beam then I could remove the relay, splice over the 2 contacts and in theory I would have both high beams and no running lights! I am not going to do any random splicing in case something would short so I am still trying to figure out the wiring.

One click on the E-brake is not a good idea. If the E-brake switch is grounded the DRL's will stay off the switch is on the e-brake lever under the center console. Do not try this on a 2k S or L car. Those cars chime when the E-brake is applied. On the earlier models the brake light would stay lit . I'm not suggesting you ground the wire, I'm just letting you know how that part of the ckt works

Default daytime running lights, belts and airbags

How are the DRL's a problem? They run at a much lower light output than low beam headlights. The foglights on my SC2 put out more light than the DRL even. I have tested every combination of lights while parked about 50' behind my wife's truck just to get an idea of beam patterns, intensity, etc. I wish the DRL were like my old VW which was low beams at 95% power plus parking lights. I never turned the lights on unless I wanted high beams. The Saturn setup is nice however as you can always tell another Saturn driver from long distances. While you are modifying don't forget to hook your airbags and seatbelts to your DRL switch.

In My 98 SL2 I:

- Pulled the DRL Relay (A very standard automotive relay, I might add).
- cut a two inch piece of wire (stripped the ends)
- pushed the ends of the wire into the relay pin holes marked 30 and 87a.
- Done.

Tada -- Disconnected daytime running lights and no more bucked tooth look.

I guess you can blame us Canadians for those DRLs. Transport Canada did a bunch of research and found that vehicles with DRLs were far less likely to be in a collision. As a result, all cars in Canada have had DRLs for many years. I believe it started in '88 or '89.

To be honest with you, I have never found them to be a problem in any kind of weather. I also feel much better knowing that the people in front of me have a better chance of seeing me in their rear view mirrors.

The only exception to the general rule of de-powered high beams is Daimler-Chrysler, which has taken to using bright bulbs located in the parking lights instead.
