If anybody is looking for bargain DRLs on eBay, sadly I have not seen any bargains the meet the safety requirements of the DRL spec. The vast majority of products called DRL are simply decorations that are typically only effective in low light or at night. Therefore buyers are being misled by dishon...

Your suggestion of connecting the headlight lead to 87 has some merit, however the headlight current is quite high and would not be a match for the ignition circuit and fusing in the supply to 30. How about using the parker lights wire instead of the headlights ? The parkers are also on when the he...

I have placed a suite of relevant DRL pdf docs on the web. One is simple connection detail for DRLs. link: http://cid-f83bf1ac32452395.office.live.com/self.aspx/.Public/DRL%20connection.pdf#resId/F83BF1AC32452395 http://www.bcae1.com/images/jpegs/relaybot.jpg Connection 87 would be live when the he...

The Philips product appears to be a good solution. I wonder why opting for 650 Candela when 1200 is the limit. From my prototype it was not hard to obtain above 1200. I note that Google have picked up on my testing. When Googling Chinese DRL. Looking at the Chinese offerings in that Google search it...

DRL photos. Installed in Subaru left DRL old, right new at nearly 1200 Candela http://lh3.ggpht.com/_Yqj2ESV1SZs/TIXLv6oazHI/AAAAAAAAAks/hwjxLQBEXWE/DRL2.JPG http://lh6.ggpht.com/_Yqj2ESV1SZs/TIXLwmk-0nI/AAAAAAAAAk0/iFXHXQ-5unk/DRL1.JPG http://lh6.ggpht.com/_Yqj2ESV1SZs/TIXLwKtEHSI/AAAAAAAAAkw/fL9OZ...

I have purchased and tested a Chinese made DRL model DL1 as sold on eBay. I was hopeful it would meet the DRL standards due to the quoted LED lamp currents. Testing revealed that indeed there is sufficient Lumens available to get to 1200Cd but unfortunately the very poor optics scatters light widely...

There appears to be confusion here. DRLs are safey devices with strict spefications and regulation that must only be on with the ignition and turned OFF with the headlights. They are bright to overcome bright sunlight. Angel eyes are usually not DRLs they are decorations. They do not meet the DRL re...

The request was for auto dimming both up and down. This is best achieved witha small 8 pin micro processor such as the AVR Tiny 25. Whilst this method has been mentioned above it can be achieved more simply than using a C compiler etc. The AVR code can be writtem in simpler Basic and then auto compi...

I would like to issue a word of caution about Australian eBay seller v-lites and DRL products. There are some non complying strip LED lights on offer and a number of products are twice the price of the same products purchased directly from China(on eBay). Importantly v-lites offers no warranty and s...

Thanks Blakey - I hadn't noticed but would have ended up with a wire needing power! To davmax - do you have any pictures of your DRLs? How did you go about fabricating the focal components? I wish I listened more in calculus classes in high school..... What is the 'DRL controller' you refer to in y...

Thanks Bandit. That is a good link. I am familiar with that article and have corresponded with the author. I recently completed a project building my own DRLs. Amazing performance with three CREE XPG R4 Cool LEDS each with Tina optics XP-G-O for an oval beam. Spaced 37mm apart horizontally. Results....

I noticed in an earlier post that a headlight was quoted as 100 Candela and min DRL 400 Candela. My headlight on high beam is 8000 Candela that seems more realistic and puts the max for a DRL of 1200 Candela in a better context. I think those numbers refer to the headlight during the day at a dista...

The lights look bright enough compared with ambient light. Remember the mention of LED life with operating temperature. Can you get access to a infra red thermometer? If so to measure the LED temp without power (ambient temp) and again after >20minutes of power. Point at LEDs and find the hottest te...

Bandit. Am I correct in understanding that this forum does not support picture uploads so that your install could be seen. What did the Aurora lights from UK cost? I guess that because there is no Aussie compliance centre the Eurocentric 23C temp test has not been picked up. I am chasing UNECE on th...
