Fits 2000 Chevy Camaro

In the photos you can see the heat damage the stock 3157A bulb caused on my 2000 Chevy Camaro with front turn signal/parking/side marker lens housing and standard 3-wire bulb socket caused. I had to replace the right and left cases and sockets twice due to the same heat damage. This time I decided to change the package and use 3157 compatible amber LEDs instead of 3157A bulbs. After reading reviews and answering questions about JDM ASTAR LEDs, I decided to give them a try. I was concerned about the length of these LEDs but I found they fit into the case with a small gap between the end of the LED lens and the bottom of the case. The stock Camaro flash module (Wagner 224 12V) does not flash as the onboard JDM ASTAR LED blocks just stay lit (standard indicator for a blown bulb on this car - if the front or rear bulb fails, the remaining bulb and indicator will remain on the hyphen stays on). My 2013 Dodge Journey flashes when the front warning light burns out, a 2000 Camaro just stays on. Other reviewers stated that they suffered from hyperflash and had to install load resistors in parallel with the turn signal to ground to trick the turn signal module into believing that the LED was carrying the bulb's load current. I didn't like the idea of adding resistors and doing some research on youtube for a 2000 Camaro LED resulted in a recommendation to replace the turn signal module with an LED compatible unit. The author's decision was to replace the standard flash driver with the Novita LL552 module. With the LL552 installed we now have a normal turn signal flash rate with a front mounted JDM ASTAR LED and a stock 3057 bulb in the rear turn signal socket. The LL552 turn signal was $6.99 at my local Advanced Auto Parts store. Camaro daytime running lights activate the "Signal" socket input, so with a 3157A bulb installed, thermal damage to the lamp and socket was the result. At night, when the headlights are "on", the connector's park input is on, and the connector's "signal" input follows the turn signal, resulting in a faint bright blink. During the day with the headlights off, the "signal" wire stays on and flashes when the turn signal is turned on, eliminating the bright flash. Therefore, during the day, the daytime running lights will activate the JDM ASTAR LED input and drive the LED with a higher current in the "signal active" state. Поскольку я устанавливал светодиодные блоки, чтобы избежать теплового повреждения от лампы накаливания 3157, я проверил нагрев блоков JDM ASTAR с помощью бесконтактного инфракрасного термометра и обнаружил, что интенсивность "парковки" привела к пиковой температуре отдельно стоящего светодиода (гнездо вниз) в 105 градусов по Фаренгейту in 15 minutes. When the power was connected to the "Alarm" pin, the peak temperature was 155 degrees Fahrenheit after 10 minutes. I found that the JDM ASTAR LED was not polarity sensitive: the devices performed the same no matter how the device was inserted into the standard GM. 3-wire socket, ground-to-ground contacts on one end and a parking light on the other end (no CK socket). So the JDM ASTAR appears to have auto polarity sensing, as rotating the LED 180 degrees in the socket will result in the socket's ground pins being connected to the JDM ASTAR's LED parking signal terminals.

Pros
  • Sleek Design
Cons
  • Negative Impression
